Does anyone have new model mustang seats in their car? If so what were some of the issue they may have run in to? I saw a 69 mach 1 with 99+ seats in his car and they looked pretty good, but they were GT seats. I know where to get mach 1 seats that look like the old seats and was thinking of what it would take to replace my old 1970 seats that are currently in the car. I know the rails underneath are different, and there are a couple hole modification for the floor pans. If anyone has done this do you have pictures of the process?
