Just installed a set of seat belt guides from a 4th gen Camaro convertible. Most do the 3rd gen guide but I think this one is better. Fastener spacing is the same. It lowers the path of the belt over your shoulder even more than the 3rd gen guide. I'm 5'10" and the belt path is perfect. If you're over 6' the 3rd gen might be better, although obviously that can be adjusted by raising the headrest. Convertible version has the split so you don't have to remove one end of the belt to put it on.
