Hey Everyone - I'm in the process of a '66 restoration and have a question for you. I have a solid set of 1967 bucket seat cores and was planning on installing new 66 foam, upholstery, and seat backs/bases. However, I do like the locking mechanism on the 67's. Is it possible to install 66 foam/upholstery with '67 back panel/seat lock button? It's going to be a daily driver (already installed 4 wheel power disk brakes) so I want it as original as possible but with a few better safety upgrades. Has anyone done this before? *Also, I'm assuming that the 67 bucket cores are the same as 66's, with the exception of the seat lock button, but please correct me if I'm wrong. Thanks in advance! Joe
