67 Fender Clips

[juliosz]

When my 67 Camaro was disassembled somewhere around 1978, the original owner bagged and tagged all of the parts. Three of these bags were marked “right fender” and “left fender” and “front grille and core support. They appear to be original as they all had equal amounts of rust. My question is since they look different but use the same size and thread bolt, is this a case of same usage but two different suppliers or specific usages for each? Between the three bags, there are 6 of each type.

Thanks
