Will a 2nd Gen. Posi rear end w/ disc brake set up from a 81 Trans am fit a 67 convertible?
I have a 79 Posi with Disc rear end in my 67 Vert and it fits great. The spring perches will have to be slightly relocated, but with a little work everything fits quite nice!
I say go for it and enjoy! Just make sure you do the Booster/Master Cyl/proportioning valve upgrade too!
