Jeff,
My experience with 64 and 65's is that yes they are the same. 2 doors/4 doors, wagons, ec's are all the same. This doesn't hold true in 66's and up however. Also just as info, 64 and 65 2 door posts and 4 doors have a different rear glass and moldings than a 2 door hardtop but the front glass is the same.
