c-clip backing plates the same as bolt in axle backing plate

Are c-clip backing plates the same as bolt in axle backing plates? 10 bolt different from 12 bolt???
Thanks

Most are interchangeable...The flange bolt pattern is for sure. It is the inner diameter hole that I have run into slight variations when swapping c-clip ones to bolt in axle rears...SOMETIMES the bolt in axle bearings do not fit though the c-clip inner diameter hole. SOMETIMES. Most of the time they work fine. WHY??? who know. The c-clip rear flange end has a small 1/8 " ledge to center the backing plate to its flange...that diameter is slightly smaller than the stock bolt in axle bearing ...sooo... there you go.
10 bolt or 12 bolt a-body f-body 1963-1972 1973-1980 are all the same with 9" brakes.
exception of the g-body 1978-1987 and 1982 -1993 s-10 and h-body GM 9" brakes which are NOT the same as any other backing plates.
If it does not fit you can just dremel it a bit to over size that inner diameter to let the bearing slide through for a bolt in axle application.
Hope this answer the question in full . Jim
