Front Bumper Braket I.D. Thread

[special-K]

I have a bunch of bumper brackets not doing anybody any good until I can identify what is what for which truck. Here is the hard part, I do not presently have a way to take and post pictures. So, I am asking for anyone with pictures of brackets they know the identity of to post pictures, or anyone with ones laying around to take pictures to post. I figure this thread can be a good reference for all to search in the future. I get half way through the pile thinking I have it figured out, then come across other variations that mess me up. Even knowing how many variations and what they are would help w/o pictures. I know 2wd 67-70 and 71/72 Chevy are two variations. Is 67-72 GMC the same? I assume the 4wds break down the same as 2wd? I would think there would be 67-70 C/Chevy, 71/72 C/Chevy, 67-70 K/Chevy, 71/72 K/Chevy, 67-72 C/GMC, and 67-72 K/GMC. So six variations? I wish I had marked these things when I pulled them!
