I did that on my car.
Mine was an 86 limited. Its not a big deal for a body shop and the 1/4 windows need to come out anyway when its getting painted so just have the correct ones on hand for the re-install. The rear window trim I havent finished yet, but Im going to take it to a glass shop so they can remove do whats needed including laying in the correct trim clips for the molding around the rear window. I also had all the chrome taken off and those rivets mentioned ground down. Not a big deal but then again I got a smoking deal on all the work for my car. Think about painting the bumpers to match the color of the car. It looks great on my white car.
