The original bumpers were rechromed with the backs sand blasted prior to plating. I polished NOS Bumper Bolts, the original
bolts had stainless steel caps on the heads as shown in the right side picture, therefore polishing just like chrome.

A NOS Grill Guard was chromed and assembled and I painted a original Front license plate bracket.

Not shown, the front and back bumpers along with NOS Fender Guards , NOS Trunk Guard and  Bumper Guards were rechromed
