GM A body 12 bolt.

[COCHEV]

my brother in law in Kansas is looking for a Gm A body 12 bolt rear for his 72 Olds Cutlass. 68-72 chevelle, cutlass, 442 or skylark rear ends will work.

any coil type 12 bolt from 64-72 will bolt in. there were different width though. but only an inch different. The 70-72 monte carlo axel will work also. Just stay away from an odd ball OLDS 12 bolt. It uses a 12 bolt cover, but really only has a 10 bolt carrier. It is also hard to get parts for.

12 BOLT available

I have a 71 or 72 El Camino I'm taking apart just for the frame. Rear axle is available. Dunno the ratio, but will check it out if you want.
