Are '71-72 Dart rear bumpers reproduced?

I could have sworn I had seen "new" bumpers for the '71 '72 Darts, but now that I need one I haven't been able to find anything except the '70 rear bumper.

I've seen the 70 ones too, but no 71 and up. Can you just get a clean core and have it rechromed?

If that's my only option that's what I will do.
