I am hoping some members can offer advice or suggestions about changing my rear bumpers on a 1974 GTV without the bumperettes. My understanding is tha the later GT Juniors used the same rear bumpers, but had stainless join cover plates installed over the two seams. I recently purchased these cover plates from Classic Alfa, expecting them to have holes for fasterners or screws on the bottom (See below). But they don't. They are flat and need to be bent around the bumper and look like cheap repros of the originals which I understand had fasteners. Has anyone used these on their GTV or GT Junior, and if so any advice on how to properly attach would be appreciated!
