was told sat that the newer caprices (b-body) were avaliable with an 8.5 inch rear that would fit directly in a metric guy said that is where his was from, what year do i look for and how do i tell the difference and do they exsist/fit.

how do i tell the difference and do they bolt right in, not worried about the shock mounts just the control arm mounts, i have trashed 3 7.5 housings this year 1 was my own fault the other 2 bent and i have missed out on 2 1/2 races due to ring/pinion faliure. wish someone had tole me that when i finally got the car to bite i was gonna start breaking things.lol.

I don't think the control arm mount angles are quite the same. I think they are close enough that people jam the arms onto them, but how nicely they move is a different story. Have not done this myself - just thinking back to other things I've read on here - maybe someone can be a voice of experience.

Hop on Speedwaymotors.com for the listing of which ratios are made - tons of places carry them - this was just the the first one I thought of.

Some metrics use a 8.5 rearend like monte ss and buick gran nationals and they all use the same arms.Correct me if i'm wrong.

The Olds 442's from the 80's had them too.
