On the brake hardware parts, get stuff from 65 at the oldest so you can have the self adjusting parts and pieces

One might wonder why I dont use the backing plates off my 66 and I briefly considered that but I have 2 interested parties who want the 66 6 lug diff and probably want it complete. I was also wondering if there were design changes in 73 and up square body trucks

As for the early c10s having pressed on backing plates is just cruel engineering, thank goodness they got away from that setup.
