junkyard haul rare find?

[1972BackInBlackC10]

so i went to look at a 72 cheyenne today that my friend found at a wreckers with the possibility of buy it but the floors were pretty bad it was more work than what i want to do

but i did leave with some parts, i got a tailgate band that is missing some letters and i lost the H some where, trim for around the handle, one passenger side bucket seat bracket (unfortunatly the seats are gone) and last but not least the rare find, im no expert so you tell me if i got a rare find, i got the brass gas tank carpet retainers all 12 of them were still in the truck plus i got all 12 screws

from what i understand these are usually mia and the ones on here for sale that iv seen werent complete sets, so i figured maybe it was an uncommon or rare find, for me it is anyways being in canada, nothing special just got a lil excited and thought id share, feel free to mock the silly canadian lol

i plan on going back to salvage some more off this truck when it dries up my socks got a lil wet taking the tailgate band off
