What to harvest when at the junkyard

I’m still fairly new to the mopar world. I have seen various posts mention certain things that are hard to find / obtain that I’ve overlooked In The past. I’d like to form a list of those parts so as to have a reference. I’m talking about the oddball things I’d never think of. For instance I’ve learned:
LA exhaust manifold washers
Slant manifold washers/triangles
Slant six truck (van?)dipstick/tubes
Rally dash screws
Power steering pump caps

Not looking to make money, just help others out. So whatever else you can think of that are hard to find, please post up
