Does anybody know how to tell a new repro from a rechromed original for a 1968 front bumper? I just turned in my originals to Bumper Boyz and got back one that looks good except there is poor machining of the edges where the bumper turns to curve around the fenders. Hard to tell unless you are right up on it. The weight of the bumper seems like the original?

Lots of them are rough, there.
