Ran into an old customer the other day and she asked if we could become Facebook friends.
Been chatting ever since. I was the only one in the store to treat her with the respect due a customer and human being.
She needed parts, I guided her and sold them. She loves the fact I never treated her like she was just a dumb woman.
Being a former shop owner I'd say 70% of my clientele were woman, just for that reason. I never treated them like dumb women. Most of them knew more about a car than their husbands.
I never dispute a customer when it comes to repairs, either.
That car is her daily driver. She rides it 10-12k miles a year on average. She knows better than I do when it's acting up or making a noise. I just need to pinpoint the problem and fix it.

Just the facts, ma'am
Tim,
Almost every track requires a bar for convertibles - even for Driver education/track days.
For road racing (wheel to wheel or hillclimb/time trial) it all depends on the sanctioning body and class. The min will be 4 point, and a certain tubing diameter and material, etc. Sometimes there are restrictions so the cars don't become tube chassis with shells. You might want to get in touch with Tim Herron (All-time racing) for the sanctioning clubs in your area. (He puts on the mopar track days at the Willow Springs and Streets of Willow. You may have seen his tunnel ram 318 Dart, which he's decided he liked so much that he's retired it from 24 Hours of Lemons. LOL.) If you are serious about road racing, also hold off on the new front brakes. Vintage classes are usually pretty restrictive, so see what the rules will allow. I'm pretty sure the Willwoods will be OK for the groups on the west coast (they're not for the groups around here - calipers must be iron). The bigger diameter disk is probably where there will be a restriction - either directly or by the required wheel diameters.

2017 SCCA® National Solo® Rules— 215
Appendix C - Roll Bars
APPENDIX C - SOLO® ROLL BAR STANDARDS
A. BASIC DESIGN CONSIDERATIONS
1.
The basic purpose of the roll bar is to protect the driver in case the vehicle
rolls over. This purpose should not be forgotten.
2.
The top of the roll bar shall not be below the top of the driver’s helmet
when the driver is in normal driving position, and shall not be more than 6
inches behind the driver.
Exception
: For Modified Category Specials (Sec
-
tion 18.4), the bar must extend at least 2.0” (50.8 mm) above the driv
-
er’s helmet in the normal seated position and a head restraint keeping
the driver’s head from going under or behind the roll bar is required. It is
strongly suggested that all roll bars extend at least 3.0” (76.2 mm) above
the driver’s helmet. In case of two-driver cars, both drivers must be with
-
in the roll bar height requirement, however only one (1) driver must be
within 6.0” (152.4 mm) of the roll bar. In a closed car or an open car with
a removable OE hardtop which is equipped with a roll bar/cage, it must be
as close as possible to the interior top of the car.
3. The roll bar must be designed to withstand compression forces resulting
from the weight of the car coming down on the roll structure, and to take
fore-and-aft loads resulting from the car skidding along the ground on the
roll structure.
4. The two (2) vertical members forming the sides of the hoop shall not be
less than 15.0” (381 mm) apart (inside dimension). It is desirable that the
roll bar extend the full width of the cockpit to provide maximum bearing
area in all soil conditions during rollovers. The roll bar vertical members
on formula cars and other single seat cars with a center driver position
must be not less than fifteen inches apart, inside dimension, at their at
-
tachment points to the uppermost main chassis member.
5. An inspection hole of at least 3/16" (0.1875”, 4.75 mm) diameter must be
drilled in a non-critical area of a roll bar member to facilitate verification
of wall thickness. This should be at least 3.0” (76.2 mm) from any weld or
bend.
6.
It is recommended that steel gusset plates be used at all welds. Gussets
should be at least 2.0” (50.8 mm) long on each leg and 3/16" (0.1875”, 4.75
mm) thick.
7. It is recommended that roll bars be coated only with a light coat of paint.
If, however, a roll bar should be chrome-plated, it is recommended that the
structure be normalized.
8. Post or tripod types of roll bars are not acceptable.
B. MATERIAL
After 09/22/1985, aluminum is not an acceptable alternate material. Cars
using aluminum roll bars or roll cages must file proof with SCCA® Solo® De
-
partment that the structure was approved prior to 09/22/1985 as provided
in this Section.
216 — 2017 SCCA® National Solo® Rules
Roll Bars - Appendix C
1. The roll bar hoop and all braces must be of seamless ERW or DOM mild
steel tubing (SAE 1010, 1020, 1025) or equivalent, or alloy steel tubing
(SAE 4130). It is strongly recommended that roll bars not be constructed
of ERW due to quality and strength concerns.
2.
The size of tubing to be used shall be determined on the basis of the weight
and speed potential of the car. The following minimum sizes are required
and are based upon the weight of the car without the driver.
Vehicle Weight (lbs.)
Tubing Size (min.)
outside diameter x wall thickness (in.)
Over 2500
1.500 x 0.120
1.750 x 0.095
2.000 x 0.080
1501 - 2500
1.500 x 0.095
1.625 x 0.080
1000 - 1500
1.250 x 0.090
1.375 x 0.080
Under 1000
1.000 x 0.060
Dimensions are nominal. 0.005” (0.127 mm) variation in wall thickness is
allowed.
3. Each mounting plate shall be at least 0.080” (2.03 mm) thick if welded and
3/16" (0.1875”, 4.75 mm) thick if bolted. A minimum of three (3) bolts per
plate is required for bolted mounting plates.
4. All bolts and nuts shall be SAE Grade 5 or better and 5/16" (0.3125”, 8.0
mm) minimum diameter.
C. FABRICATION
1.
One continuous length of tubing must be used for the hoop member with
smooth continuous bends and no evidence of crimping or wall failure.
2. All welding must be of the highest possible quality with full penetration
and will be subjected to very critical inspection. Arc welding, particularly
heliarc, should be used wherever possible.
D. BRACING
1.
It is recommended that braces be of the same size tubing as used for the
roll bar itself.
2. All roll bars must be braced in a manner to prevent movement in a fore-
and-aft direction with the brace attached within the top one-third of the
roll hoop, and at an angle of at least thirty degrees (30°) from vertical. It is
strongly recommended that two such braces be used, parallel to the sides
of the car, and placed at the outer extremities of the roll bar hoop. Such
braces should extend to the rear whenever possible.
3. It is suggested that roll bars include a transverse brace from the bottom of
the hoop on one side to the top of the hoop on the other side.
2017 SCCA® National Solo® Rules— 217
Appendix C - Roll Bars
E. MOUNTING PLATES
1. Roll bars and braces must be attached to the frame of the car wherever
possible. Mounting plates may be used for this purpose where desired.
2.
In the case of cars with unitized or frameless construction, mounting
plates may be used to secure the roll bar structure to the floor of the car.
The important consideration is that the load be distributed over as large
an area as possible. A backup plate of equal size and thickness must be
used on the opposite side of the panel with the plates through-bolted to
-
gether.
F. REMOVABLE ROLL BARS
Removable roll bars and braces must be very carefully designed and con
-
structed to be at least as strong as a permanent installation. If one tube fits
inside another tube to facilitate removal, the removable portion must bottom
on the permanent mounting, and at least two bolts must be used to secure
each such joint. The telescope section must be at least eight inches in length.
G. INSTALLATION ON CARS OF SPACE FRAME AND FRAME
-
LESS DESIGN
It is important that roll bar structures be attached to cars in such a way as to
spread the loads over a wide area. It is not sufficient to simply attach the roll
bar to a single tube or junction of tubes. The roll bar must be designed in such
a way as to be an extension of the frame itself, not simply an attachment to
the frame. Considerable care must be used to add as necessary to the frame
structure itself in such a way as to properly distribute the loads. It is not true
that a roll bar can only be as strong as any single tube in the frame.
H. ROLL CAGES
It is recommended but not mandatory that all cars utilize a roll cage as de
-
fined in the current Club Racing GCR Section 9.4, Roll Cages For GT And Pro
-
duction Based Cars, or Section 9.4.5, Roll Cages For Formula Cars and Sports
Racing Cars.
I. ROLL BAR PADDING
Braces and portions of the main hoop subject to contact by the driver’s or
passenger’s helmet, as seated normally and restrained by seat belt and har
-
ness, must be padded with a non-resilient material such as Ethafoam® or
Ensolite® or other similar material with a minimum thickness of 1/2" (0.50",
12.7 mm).

That is why Mr. Mitch said you are an exception to the rule and I can agree with that.

Just the facts, ma'am
You talking SCCA autocross, timed speed or racing?
For road racing, there are regional vintage classes but not all regions have them. I beleive the other SCCA class will be "Open". That's what Jim and Robert Benson run in. Although occassionally they do vintage events. In mid-west there's also Mid-west council of sports car clubs. They have high speed autocross - a form of timed track events with lower risk than road racing or hillclimbs.
solo timed road race and some autoX. not door to door, bumper to bumper racing.

OK. Roll bar will be good. For autocross, E Street Prepared and classes bases on SP restrict the frame connectors and caging - that may include "Street Mod" I haven't checked the current iteration. C Prepared does not restrict connectors, nor caging too much.
wonder if i can run a removable cross bar

Well, take into account, that I also was raised by a momma who would kick my *** if I did anything different. Lol

for autocross, you can run no bar so my guess is yes unless they think the way its done will be a hazard
Not in an open top car, like mine.
just got done reading your website, pretty cool
Mattax
Just the facts, ma'am
Yea. I think those days are gone. Even in 'stock' classes there's been a minimum roll over protection requirement for 'verts including your helmet can't be taller than your bar. Probably a good thing althouugh roll over accidents are very very rare in autcross.
i watched a C5 roll a few years back. Though it was pure mechanical failure, something broke in the steering mid turn and it slid sideways off the track and into the grass and rolled over. no one hurt but his black vette was screwed
Decided not to mess with dropping off the Fury today. It really is just water, not slick-feeling nor does it taste like coolant. Will drive it to work and see if it leaves a puddle. Nap time now though.
Was it salty? Could it be from the undercarriage?
Hey Hoppy, I got ahold of a older Filko catalog now. It's from about 69-79 with tune up, distributor, starter and charging system parts. Let me know if you need something looked up.
Another day. Another doctor.
Good news less meds. Took me off two MS. Meds.
Blood pressure 120 over 72.
Not bad for a fat old guy.
He did say I can do this test instead of the scope.

Been waiting for the RRHF thread to pop back up. Since it hasn't I see among the inductees is Dire Straits.
April 14th, 2018 in Cleveland is the ceremony. I'm thinking I have to go to that, its on my bucket list and time grows shorter & shorter--------------

Talked to a Cleveland native about it. Cleveland appears to be a really neat city, kind of like Chicago. I see they are doing a major rebuild and addition to the RRHF.Still can't rap my head around how Cleveland ended up with that Hall of Fame.
I just gotta go, my wife even bought me the book about it all. With Moody Blues and Dire Straits getting inducted it will be a week long party!!!
