I purchased a 72 GS, Stage one last year that needs full restoration. It is also Hunter Green with a green vinyl top. The interior is White buckets with black carpet. I plan on putting the vinyl top back on only because I believe the car should be original. My car is 1 of 627. Again this is my two cents (Like everyone else has said) I would leave it completely original including the vinyl top. What a conversation piece it is going to be with it back to original. Buick was famous for weird colors and combinations. So if you don't put the vinyl top on, are you going to cut the rivets off and fill the thru holes for the moulding or are you just going put the moulding on with no top?
