I have been in search of a usable dash that hasn't been chopped for a non stock style stereo.
Of course the parts were buried in thorny vines but a little clearing and i could get to them. The 1979 Mustang in this photo is what my car's original color was. Someone took the sport steering wheel already.
The difference between a 1979 Dash and an 1985 Dash is below. Upper is from a 1979 which was equipped with an 8 track stereo.
