Hi Dave. Might take you up on this... was your car undercoated? It's hard to tell with your car being black, and undercoating being black.
These '72 Swinger 340 Specials, Crosstown versions - Danny and Joel, your's might be different, but they just had the rear wheel wells and on the front, there was a taped-off swath of undercoating on the inside fenders that went up to where the fender and apron were bolted together - which I have reference for but it's the area behind the upper a-arm that I don't know exactly how they applied at the factory? I know it wasn't the full wheel well, just the area behind. If your car was as described, could you give me some pointers? Would be greatly appreciated. Thanks in advance
