The one I have is showing some minor trauma and I'm not sure if I can fix it.

If you can't there are plenty who can so do not scrap it....
First thing ya gotta know is GM used the same type bumpers but theirs was called Endura-Bumpers... And since GM out sold Mopar by better than 10-1 when your looking for restoration info using the GM lingo helps... There are services to do it for you & theres a tom of DIY threads...
A good OE bumper fits way better than anything I've ever seen from Gene Gregory... Fact is a buddy use one of his rear bumpers & the fit was so bad he wound up cutting both ends off, shortening the bumper core, welded it back together then did a repair to the elastomeric finish...
