Early Vega rear ends

Postby smoby » Sun Sep 22, 2019 12:37 pm

What year did GM start using the 7.5" rear end in the H-body? I'm building a '74 Vega wagon and I have the rear end from a '75 Monza 5.7 Town Coupe. Could used some help identifying both, hoping the Monza is a 7.5 being a factory 350 car.

The Monza rear end is the torque arm variety. To confirm it is a 7.5 the left front side of the differential has four pass through bolt holes for the 7.5. If it is the smaller 6.5 there will be 4 threaded holes. I was looking for a picture but couldn't find one to post.
