I need help in identifying some parts

[belmont]

I have a couple of NOS clamps that I found in my stash parts that I would like to know what I have here. The first one has one bend sharper than the other and the sharp bend is 1" long, the other is 3/4" long. I included a known NOS 1063-37 (65512-37) clamp as reference in these photos. The second one has the same bend angle and one is 3/4" long, the other is 7/8" long. Both clamps would use a 5/16" bolt.
Next I have 2 brackets I can't identify. They are 1/4" thick parkerized steel, .850" (27/32") wide have 5/16" hole, are 3" long, and have a 1" offset height.
Last I have this offset bracket that I think is for a windshield. It is 4 7/8" overall, one leg is 2 7/8", the other is 2 1/4", the holes are 5/16", and it looks like it is parkerized.

Any help you can give would be great.

Thanks, belmont

Thanks Rubone, never would have guessed something that heavy duty hanging hidden off the back fender of a panhead. I don't have one of those bumpers of either of my bikes, so thanks for the info. Without part numbers some of these parts really are baffling when paging through a stack of parts books.

The bracket is supposed to be a transfer point of rear impact to the rear stand. rear bumper.jpg

Makes sense now why they are so heavy duty. The rest of that bumper is purely decorative. That also clears up why it wasn't used on Duo-Glides, no rear stand to diffuse the damage.
See what you learn when you ask questions.

Thanks, Rubone
