As I said earlier, I replaced the roof skin with a rust free one from a '74 Charger. That car had a canopy vinyl as well but the '74 molding and the '71 moldings are in different locations. I had to grind off the weld studs from the '74 position and weld some new ones on in the '71 position. This necessitated the use of my uni-spotter to weld them on.
