Hi guys i have on my backyard a Chevy 51 Rearend and today my curiosity made me take off the cover ..i raise it and made the wheel spin and in the gear came with 37/9 theet...which gives u a 4.11 Ratio and thats a fast ratio ,..the question is can i swap the inner components into my 7.5 housing ?
or its a 8.2 a 51 chevy rear end ?
how can i tell it is a 7.5 not by lookin at it ..i wanna check with a ruler
Thanks

 

The 7.5" like we have in our 3rd gen F-bodies was a new series when it came out in the mid-70's. Nothing from the '51 rear will fit it.

Sorry.
