I found a guy selling a rechromed 52 bumper, and it just so happens that my 53 bumper is in dire need of rechroming, as well as having a number of small dents, bends, and dings.

I would be extremely happy if this were a bolt-on replacement, but he's 350 miles away and pictures just aren't quite enough to tell for sure...

 

I do not believe the bumpers are the same?

 

I was wondering the same but for front bumper. I have a 51 and I want to put a 53 front bumper and grille in.
