Building a 77 Monte, need to know if a 12 bolt from a earlier Impala, or other car, will swap [ better gear selection]. Would go with a 9 inch but rules won't allow it. Merry Christmas Ya'all..........

I tried this on a '76 Cutlass, the lower trailing arms bolt right up, the uppers are a problem. The car you have the upper trailing arm spread from the center section to the mounts in the frame, the rear end I had,a 12 bolt from a '65 Impala, the upper trailing arms were straight to the frame with a panhard bar. I felt it was a lot of work for a little gain.. if any. In the end I wished I'd not done it. loojack
