I got a pair of ACC repros for my car. They came with the rubber glass-to-molding strips and the finish was good, but they were a tad too long and I had to bend them and elongate the screw hole
. Fortunately, that is below the belt molding and weatherstrip and it won't show. I've learned if you can afford the Genuine GM part, buy it--although beware of GM NOS chrome emblems--they're poor quality compared to the better repros. Our dealership sells to Ausley's Chevelle Parts, and I've seen some pitiful GM emblems
. Good luck!
