I'm trying to find a correct aftermarket replacement rear bumper for my '70. It has the pair of bumper guards. I bought a bumper from NPD, but it's going back because their item does not have holes to mount the bumper guards. I called Rick's, and theirs also lacks the holes for the guards. I could do without the guards, but then the holes would remain in the lower valence. Has anyone found a decent aftermarket rear bumper for cars w/bumper guards?
