Rear bumper question

[metalman]

Does this look like a stock rear bumper from a '72?
I got it with my truck but not sure if it was the original for it.
I am going to be selling a bunch of crap, Uh, i mean some quality used parts from my truck that i don't want or need, and i want to make sure of what i got as far as this bumper is concerned. It looks ratty but i think it is in pretty good shape. I never payed much attention to it until i need to move it for some reason and then think i need to get rid of it. it is heavy as heck.

thanks !
