I understand the difference between a 10 & 12 bolt rear end. Is there any performance ordifference between the two? If so which is better? I have a 67 SS Convert. Thanks

You might want to toss in other environment variables the Camaro is subjected to when calculating things like performance with 10 or 12 bolt rear ends.

I would have to say is that there is not much difference unless your going a 150+ MPH and the differential gear cluster explodes.

The race fans aren't as likely to get hit with shrapnel if you get the 12 bolt.

I think the same gears fit in either one and it is my understanding that they are interchangeable.

Haven't worked on a car in years but I use to be a smog tech. And I have built 3 Camaro's so far. Two 67s and One 68.

Stopping by this web site has got me going on Camaros again. Thanks.

I just wrote a whole page explaining the performance issues throughout the automobile.
I'll post it later along with my favorite Camaro race story.


Good luck with your Camaro.

I just typed positraction into the msn.com search engine and found tons of resources that could help answer your questions.

12 bolt internals and 10 bolt are not interchangeable. Maybe some shims, bearings and seals but not much else. The axles are different also.

10 bolt ring gears use ten bolts to mount ring gear,12 bolts use....... twelve bolts.The diameter of the ring gear is also different,8.250(?) & 8.875.
