For anybody that has done this, what size are the rivets along the top where the latch is? I know 50resto sells them but it doesn't say what size they are. I picked up a cover and the guy gave me some rivets but there are no guns that I have found that will accept a rivet that size. They look about the same size as the rivets that are on the cover now. I'm not gonna go spend $100+ on a rivet gun to shoot 3-4 rivets.
