I’m building a street/strip camaro and plan to use a 12-bolt rear. I got the rear from the owner of a highly modified ’67 camaro used only for drag racing. He uses Dana rears, and haven’t used the 12-bolt since 1972. Now I got the bare 12-bolt housing, axles, and the original 4-series carrier. The 12-bolt is in great shape, even has that weird anti-hop bracket used on some ’67 camaros. My questions are: Are these rare? Would it be a shame to cut it up and use C-clip eliminators? If so, what's it worth? I feel a little quilty chopping the ends off.

I would have to agree. Dont cut it up, save it or sell it. Moser has a all new 12 bolt complete with gears and posi for $2200. Or i know of a camaro specialty shop called camaro specialty in East Aurora New York that has lots of 12 bolts for $1400 complete. They might be interested in your 12 bolt. You can find them on the net. serch for camaro specialty in East Aurora.

12 bolt is Chevy-ese for the 60's-70's 8.5" heavy duty rear. The 12 bolt refers to the number of bolts that hold the ring gear to the carrier. Coincedently, it's also the number of bolts that hold the cover to the housing. 10 bolt is the standard duty rear.

forgive me if I am wrong, but I think that the 12 bolt is actually an 8.75'' unit.

Marktat, don't cut up that rear axle.

What's you're price? Email me at [email protected]

Boys, help out Clueless, at 6 o'clock position looking at the rear axle from behind the car, if there is one bolt, then it's a 10-bolt rear axle, if there are two bolts at 6 o'clock, then it's a 12-bolt. But I believe she's going to have a 10-bolt 7.5 inch? axle.

Keep the questions coming Christine, that's the only way you'll learn.

Yes, and if I am not mistaking, a 10 bolt is either 8.2" or 8.5".
(I hope I'm not wrong on this
)

By the way, what are C-clips??

C-clips are items removed from inside the diff carrier to allow the axle to be removed from the housing.

They are shaped in a "C", these devices are the only item holding the axle, tire, brake drum/disc in place.

Don't forget that the 12 bolt is very common in 69-72 Chevy/GMC 1/2 ton trucks and Blazers. Not sure if tube diameter/casing is the same as a car ...but it might be..and if you were going to cut one anyway, they can be found cheap. A lot of the truck guys sell them to install a 14 bolt. I did, and sold the 12 bolt for $200. May want to check places like ColoradoK5.com forum under parts for sale/wanted. Good luck. JT

The 12 bolt truck rear end is different and not as strong as the 12 bolt car rear end. The Impala 12 bolt is the best one to modify to fit a Camaro. Don't mess up a Chevelle housing either.

Marktat,

If it's completely rebuilt, I think you could get atleast $1200-1400 for it.

I paid $1300 for mine a couple of years ago...
