If I decide to add a vinyl top to a car without one, does anyone (aftermarket) sell the chrome trim that goes along the bottom edge and below the rear window?
FYI If you are not going for 100% stock appearance, any shop should have multiple styles they could use to trim out a newly installed vinyl top.
There's one set on eBay right now. http://cgi.ebay.com/70-72-BUICK-SKY...r_Truck_Parts_Accessories&hash=item1c162814bd
My '72 parts car has an aftermarket set-up on it. Someone added a vinyl roof sometime after it left the factory. It's been a while, I'm thinking it's a two piece set-up. One piece along the side with the bend in it to go around to the rear window. One joiner in the middle. Plastic clips held on by screws. Chrome is showing it's age. Your welcome to it, just cover the shipping. This would be a genuine "add-on", maybe from a glass & sunroof shop, back in the day.
