Guys.........I've been checking a car today to discover the gear ratio, and did it exactly like I've done it for 40 years........One spin of the tire to ? turns of the driveshaft.......... My question is as stated........ What's the highest ratio you've ever known in a B-Body from the...

Guys......... I just got an estimate for a set of Yukon 3.23's installed in my 489 case and properly set-up, "in the car".......My gears are just too noisy for words.....as a matter of fact, I have words with 'em every time I take the car out of the driveway. They quoted me $850. in the...

I installed a B-Body 8-3/4 in the 67 Cuda a while back.......I changed out the wheels a few months back to Cragar SS (I HATE puttin' these stinkin' things back on the car...they're miserable)........... Anyway, I trashed one of my studs.....would've sworn I had it right and gave it only 60#...

A while back, I designed a shifter mechanism for my Dart Sport that utilized a cable shifter and adapted a Hurst Pistol and boot for the auto tranny......Looked killer, and worked great..... I'm ready for the same conversion in the Cuda. My 67 Cuda has come a long way, and I'm ready to finish...

A while back, I had my original 67 Cuda speedo rebuilt and calibrated by Redline (If I remember right).......They seemed to do a good job......Put it in the car with the original cable and it worked fine.....BUT, I drove the car VERY little. After 3 or 4 years of 200 miles per/year if it was...

I have a 904 in my Cuda, just rebuilt........The shifts are nice at cruising speeds, but really lack the feel of my former cars....... I want a very firm and solid shift, especially from 1st to 2nd, lots of torque transfer..........no milk toast........I love to shift the car, both up AND...

I know some of the things that can cause rearend gears to howl or sing in an annoying way, but I wanted to put this out there for you guys to comment on...... It's a common problem I've run into when restoring old Mopars, and was wondering if we could lay out some of the MOST COMMON causes...

QUICK QUESTION: I have a 67 Cuda that needs a 7-1/4" axle (wanna change it out instead of having a new bearing put in....too much dough for what it is)....... I also HAVE a 1976 A-Body (Duster) 7-1/4 complete with good axles and bearings...... WILL THE 76 PARTS INTERCHANGE WITH THE 67...

I have a 7-1/4 rear in my 67 Cuda...........OK though, it's just a cruiser.......I have a nice 8-3/4 all rebuilt and painted ready to go in the Cuda OR my Duster project (I'm torn.......)..............NOW, after jacking up the rear and running the car at idle speed, I've found some...

I'm swapping out my column shift in the 67 Cuda for a Hurst floor shift...... On my 904, there is a shifting "arm" that the final stage of the linkage hooks to....very simple to unhook everything and attach the new cable system....BUT, on a 67, what else do I need to do relative to proper...

I want to replace my front driveshaft yoke with a brand new one......a good one.......360/727.......... WHERE? Tranny shop? Summit?

Well, the verdict seems to be IN on the 727 vibrations that were driving me NUTS on this particular build. It's a swapped out 360/727 combo which was shaking the car apart, and destroying tailshaft bushings. We had a new driveshaft built and balanced first.........installed it, but the...

Can anyone tell me the correct and proper angle at the driveshaft / tailshaft connection? A tranny guy has told me that I have too little on my 360/727......it is pretty slight.........How much difference would raising the back of the tranny a quarter to half inch make relative to possible...

My gremlin is back...........Joy, Rapture............. I have a 727 (A-Body) that's a real peach...... Chronic harmonic vibrations, that get worse over time (a SHORT time)........ I just had a new bushing installed on the tailshaft....old one was beat to death and rattling like...

I'm at wits end........... If I told you the number of old Mopars I've worked on that have vibration problems you'd think I'm nuts (probably do anyway.....oh well..)........ The latest is a 360/727 combo that is making me crazy. When I got the car in the shop it had u-joint...

Well, I decided to have a local shop put the car in the air and take off the tailshaft assembly to see what sounds like "marbles" in there.......As I said earlier, it sounded like an extremely worn bearing, and was getting worse.....the nioise was directly under the hump by my shifter...

OK Guys........ I have the car (Dart Sport) in the garage, and I'm ready to tackle the tailshaft bearing problem if I can get some clear step by step directions on it....... I posted a while back that the bearing sounds like it's rattling pretty bad in there...the driveshaft was previously...

Guys......... I'd like to find an 8-3/4 rear that will fit my 67 Cuda without a bunch of cuttin' and weldin'........Right now it's a 904 / 7-1/4........I don't mind the tranny, but the rear could use some help. It would be nice to find one that will bolt right up......... Are there any...

Guys........ I have a 727 Auto that was hooked to a driveshaft which was out of balance....it ate up some u-joints, and vibrated & made you crazy.....didn't drive it much.....I had a new shaft made and balanced, and installed it....Nice.....ALMOST all of the vibration is gone, but NOT...

Hey guys........... I just installed a custom fabricated shifter in the Dart Sport........ Long story short.....We had to use the Hurst 6 foot long cable due to the configuration.......we routed the cable across the transmission pan to save it from sharp bends or kinks, and used 7/16"...

Guys........ Can anyone tell me what the correct measurement would be from the actual end of the tailshaft housing to the center of the front U-Cap?? Mine seems to be sticking out too far....just don't seem right.......I notice a bit of "play" as well there when I push up on the...

Guys......... I'm working on a 74 Dart Sport 360 clone......... It's now a 360 to 727 to 8-1/4..........They shortened the driveshaft from the looks of it, and it feels a little out of balance.........we just changed the universals..........bad............we think the imbalance knocked them...

Since we got some input on 8-1/4's, I thought I'd ask about the 7-1/4 rears on A-Bodies.......... I've seen quite a few of these on cars at shows and cruises, and the chrome covers are hard to miss from the back........ Some guys have told me about their Posi's and gears they've put in, and...

OK guys............ I've ALWAYS run 8-3/4 rearends in my Mopars....ALL except my little 67 Cuda.....that's just a light duty, and it's gonna stay that way........a real survivor car. BUT, the dart Sport I just picked up has an 8-1/4 rearend........it's a posi, with 3.55...

In converting to a new floor shifter with cables, and hooking up to a torqueflite, can anyone tell me what kind of trouble we'll run into as far as the stock neutral safety switch and the like? The new shifters say they have a switch in them.........are they made to hook up to our existing...

Guys, I know there's some info. here on converting an auto/tree "bell" to the standard shift bells.........Could you help me out here?........ I think there's a truck bell that will convert the early 70's columns......I'm working on a pistol shift fabrication (that looks like a 4 speed...

This has probably been covered here before......... I have a nice 1972 904 behind a mod-318 with a 3.55 posi......I'm just tired of not having another gear for cruising...... I've considered a new tailshaft overdrive, but it just seems too expensive........... Can someone tell me more...

Guys, it seems to me that I changed a gear at the transmission speedo inlet a long time ago (too long......) in order to match my speedometer to the 4.56's in my Charger.................... A while back, I was told that the only way to match my speedo was at the rear of the speedo itself, by...

Hey guys............ We took in an 8-3/4 for a rebuild a few weeks ago...actually a month ago....it was whining something fierce on deceleration....we've brought up the topic before on this forum. Instead of just adjusting it, I had them put in a new ring & pinion set and bearings........I...

I was wondering if there might be a thread with illustrations, OR a site / publication available for A-Body enthusiasts, that will show them how to install a shift-kit in their good 904 transmissions.....(OR 727's, for that matter)............ From what I remember back 35 years ago, it was...
