80 Tbird and aftermarket parts July 15, 2019, 04:06:37 PM Hello, first post. I have a bone stock 80 Tbird that I want to swap a stout 302 into. I notice when searching the aftermarket for parts, most things for fox’s seem to list for Mustangs 84 and up. Will later fox mustang headers and k members bolt to my car? Rear ends? Can someone tell me the structural differences between my 80 Bird and later fox Mustangs? Thanks, Tony.
