Will 65 crossmember fit

Ah, I see, sorry - my mistake.

I had to replace a section of the torsion bar crossmember on my 73, which I think is what you are talking about - correct ? Mine wasnt rotted, it was chopped in two, by some butchers that installed a B body 4 spd, and made a sleazy hack job of it. Ugh. Unbelievable what some people will do

Probably any crossmember from 67-76 will likely work fine. The donor car for the replacement section in my case was from a 67, but I only needed the center part of it, so be sure to take measurements.
