I owned a 68 fast back in 1979, bought a door for it from a coupe, so I have a passenger door glass for a 67-68 coupe with factory tint in really nice shape from a Colorado car. It hasn't been on a car for 28 years. If you need it let me know.
My father is not into the internet; but his is into MUSTANGS big time and has lots and lots of parts. I'm not sure he has what you are looking for; but you can call him if you'd like to see if he can help you. His name is: Gene White Phone is: 814-756-3170. Tell him Cindy gave you his number...
