New to me 67 3/4 ton 4x4 longbed

[trapperjack]

little back window, gotta love it. I have a 68 panel wagon to park it next to, have been not too active on that part of the forums. i'm sure I'll be asking some questions and picking some brains in the not too distant future. won't be picking it up for maybe a month or 2, but am starting to round up some stuff i'll need for it, and trying to figure out year model differences. I know 67-72 are basically the same, hood/grill/fender differences, but needing to know a few things . bumpers front and rear, 1/2 ton to 3/4 same? Is 71 or 72 when the lights went in the bumper? Doors through 67-72 the same? how hard to find rear leaf springs/shackles?
details later, and photos after i figure out how to smallerize them, they're huge.
