Can someone help me identify NOS Parts
 

Howdy, A local chevy dealer was going to throw away a pile of old parts. I grabed them, I am having some trouble identifing them. Right now I have pics of just piles of parts. The parts have some org tags from GM to a Walts garage in kent CT with some p/ns. I think the parts are for cars and trucks. for example
Bumper p/n 131359 I have 2pcs
front latch pan? p/n 2712201 2-3pcs
Half hood or fender pc p/n 3688053 5-6pcs
Thanks for the help.
Pat
