I got the go wing from a buddy that picked it up from Year One. It was the cheaper version. Will that require some paint? Do I have to cut the inside of my trunk lid to mount it? The lid I from a 1972 Cuda.
No cutting required, the provisions for the mounting should be there.
Not sure about paint... probably not
If the wing is a cheap aftermarket, it's probably going to sag in the middle. I've been thinking on this after seeing several saggy wings.
If mine were sagging (which it's not), I would try elongating the mounting holes towards the center of the decklid and when you mount slightly pinch the wing legs together and kinda put it under tension with a slight arch.... doan know if this will work but IMO it would be worth trying with a cheap wing before buying a new one.......
