Was kinda wondering how rare or hard to find are these. I mean like are they diff to get cause once you get one you don't let it go or what. Are they desirable? I don't know much about the 60-66 years but would like to find info on what are the hard to find parts and what is it everybody would like to have for their trucks. What exactly are the hard to find parts or the rare items that everyone would like to have.
