Hello all trying to clarify if one, both or neither of these lower bumpers are GM manufactured.






The corroded ones on the right came off my 1972 Vette and the ones on the right are the used replacements. I cannot see any kind of markings on them which I find strange since GM seemed to mark everything and both have what I consider "sloppy" welds, but what do I know.
The replacements rears were cleaned up and painted by me and bolted up without any issues. So can anyone tell me if these are GM manufactured and if so what identifies them? Thanks Ike

Anyone???? No thoughts? Are these marked in some way by GM? Greatly appreciated!!! Ike

I do not remember seeing any markings on mine when I had it off to repair a stripped mounting nut.

Jhudec, thanks for the response. I am a little surprised in that GM and the subcontractors seemed to mark every little piece. Mine had some surface corrosion on the inside so I assumed my marks may have been obliterated. Thanks again!!!!
