To the guys who contributed the information on this thread, would you give me permission to quote your replies and make an article about this for the Buick Bugle? I think it's been a good learning experience, with a lot of good information that isn't always available. and I can document it with photos of parts of my car. It would be good publicity for this group, I think.
What would REALLY make it a great article would be to match the photos of parts of the Gran Sport with photos of the same areas on a regular '65 Skylark or Special. Anybody have access to one? If so, take photos of the frame, the radiator, the battery tray, the side moldings, the roof trim, etc., and email them to me, and I will put the article together.
