I have a 67 Barracuda and recently did the later style disc brake swap up from giving me two different bolt patterns. While knowing this kind of drives me crazy I was planning on running factory style steel wheels in a 15x8 on the rear. Wheel Vintiques offers these rims in a SBP. Not converting would save me the cost of new axles and the 10x2.5 or 11x2.5 drum setups and could be utilized to purchase a much needed suregrip.

Looking for any advice as to if there are advantages to the swap other then the larger drums and increases wheel selection.

Thanks

You could use wheel adapters. Now u gota have two spare tires.
 
Contact Dr. Diff his conversion axles work fine.

I’ve looked at Dr. Diff and if I decide to complete the conversion I’ll definitely go with his products. I’m just asking if there’s any kind of added structural integrity, or anything else I’m not considering.
 
I bought a spare rim with the dual bolt pattern to solve my problem. I have the large bolt pattern on the front of my Cuda (4 1/2") and a Chevy 10 bolt rear end (4 3/4"). The spare rim has both bolt patterns and I'm happy!!

That’s a simple solution I hadn’t thought of. Thank you for the input.

The axles are claimed to be stronger, I have had good luck with them.
Also he has different set up so I was able to use big bolt pattern 7.25 backing plates and all the brake hardware when I changed out my small rear for a 8.75 so the cost got cheaper real quick.
 
Advantage? On my own stuff, I always go SBP when possible.
All of the parts that surround a SBP setup are smaller and lighter, and weight is my primary concern.

And Tony gets ALL of my SBP wheels, axles and everything once I switch over soon. :)

Strength, ofcorse it depends on how much power your Engine's making, if its stock then your probably fine, other than just knowing its Goofy (having to deferent bolt patterns) id spend the money and just do it Right !! you wont regret it !!

You need a spare with 4" and 4 1/2" which nobody made. The spare wheel Trebleg mentioned is a dual Mopar/Chevy bolt pattern. They made millions of those.

So I'll guess you still have left hand threads at left rear, 7/16 studs left and right rear, thus different lug nut sizes front and rear. A pair of adapters would solve some of it. One spare and one lug wrench at least. Then you would never want to use that OEM bumper jack to change a flat anyway so...

I have 2 small bolt/ drum brake cars and haven't switched to big bolt disc yet. The Dr. Diff axles sound like the way to go. I'll have to keep those in mind if I convert.
 
Wheel choice for the most part.

With the SBP stuff you need new wheels or adapters. Quality adapters are not cheap.

with BBP stuff you needs, axles, brakes and wheels. Worth every cent IMO. Switching from SBP to BBP is one of the first things I do to an Abody. IT allows me to put a decent fitting and looking set of wheels and tires on and upgrade the brakes. My current car came with drums up front so it made sense to upgrade those anyhow.

I'm not finding the axles on their site. The big bolt/Green bearing axles aren't for conversions or redrilled drums.

You should tell us about all the 7/16s wheel studs you've sheared

I haven't. Like Mother Mopar, I ditched that ****. Is it adequate, you bet; far better than the four lug trash on other cars. But I subscribe to factor of safety. There's more to life than straight line speed.

Now, technically speaking, I do still run small pattern..... on my Neon.

And bigger brake shoes, I think.

THE benefit of upgrading, but not directly asked. Sign me up!
 
I go with BBP all of the time when i fix up these cars.
The SBP stuff is weaker, harder to find in good shape, more expensive when you do, and generally a pain in the ***.
The only time i would stay with SBP is if i was restoring a car to factory stock on a rare A-Body.
Wheel selection is a lot better with BBP, but you can get custom made wheels like you mentioned.
And, if you plan to run some healthy sized sticky tires and get good traction and you have an engine with a lot of torque, those shitty 7/16'' studs won't cut it for long.
Do yourself a favor and go to BBP all of the way around.
You will be money ahead in the long run..............
If SBP was so great, why did Chrysler go to BBP on their '73 and up A-Bodies with a small block and performance cars?
Because it was better, and cheaper.
 
Lh lug studs are good.


But rh is better.


Why run four inches, when you can run 4.5"?

Why go to ten, when you can go to eleven?
