most people end up going with a Dana 60 or ford 9 inch rear end eventually , so just start there , Chevy axles are prevented from sliding out by a c clip that is adequate for street use , NHRA will not allow them so the axles must be modified .places that sell performance parts will know where to get rear ends , also check the advertisers in hot rod mag. good luck , be safeMost GM 10 bolts had bolt-in axles at the outer bearing. Even if the axle broke, the wheel would stay on. 12 bolt rears used C-clips on the end of the axle. If you break an axle, the wheel leaves the car. So NHRA requires the eliminators, which must be welded to the axle housing. The GM 8.5" 10 bolt is a good one, good for 500 HP in a moderate weight car.

The other 10 bolts, the 7.5" and the older 8.2" are garbage. Watch out for them, and the other oddballs, like the Olds type "O" rear. They're weak, and parts are hard to find.

Find out what you have first. As the other poster said, the Ford 9" is the standard for performance rear ends. Parts are available, and Moser or Currie makes 9" housings to fit GM cars. I run one in a '67 Pontiac, and its great. Entire custom setup was about $2,000. Came with 31 spline axles, 9" race case, detroit locker, daytona pinion support, etc. Just modify the stock GM backing plates, and you can use the stock GM drum brakes. Its a bolt-in swap and about bulletproof.
