Looking for Rear tail light mount

I am mounting what appears to be original or at least older tail lights and signals on my truck. They were in a box of odds and ends that came with the truck. What I am missing is a matching mounting bracket.
I can have a set of brackets made but I wanted to see if anyone may have one like this that they are not using and would like to part with.

a few more pics

The "arrow" signals were likely a GM accessory. BUT as far as trucks went in those days, IH and others used a lot of common parts ["Guide" was a GM brand that built lamps and parts for IH].

Those brackets you have look to be very close to original IH tail light brackets. Unfortunately, when I sold my '66 1100 parts truck, I let the brackets for the small lights that were on the bed go with the truck, instead of keeping them for the '51.

The bracket looks original although I don't remember it having that large slot. Memory is getting shaky, so maybe it did, I don't recall for sure. However, way back in the '70's when I put a second brake light on the right side of my truck, I used a piece of flat bar that was about the same thickness and width as the original bracket and fabricated two new brackets, one for each side, so they would match. I cannot begin to tell you where the original bracket ended up. Wish I could help you out with it. About the biggest difference in what I fabricated and the original was the lack of the stiffening crease that is in the middle of the bracket. Those are stamped in the brackets with a bazillion ton press and I just couldn't find one of those with unscheduled time available. I suppose you could cut a notch across the bend and weld in a small piece of angle to create that stiffening crease. Or just trim a piece of angle and weld it in forgetting about the notch part. Or a triangle shaped piece of flat bar. Just a few thoughts.

Thanks Buzzman and Wew5.

I know I can make up some new brackets and may end up doing that. Since I am in no hurry, If someone happen to have one laying around it would save me some effort other than prepping it for paint. Yes that pressed in angle brace would be tough to duplicate. I would tack in an short angle stiffener.

Rich, you might want to check with the classified section of this website f you haven't already. I remember somebody who advertised they had bought a warehouse or similar and had a lot of NOS parts. I never got any response about an R-series hood ornament, but it couldn't hurt to check to see if they have a NOS twilight bracket. Never mind, I just checked and that warehouse ad isn't there anymore, still it wouldn't hurt to post an exterior parts wanted entry down this Board Index page. - Bob

Thanks Bob, I'll give that a try.

Mine had the slot cut in too, original does not, I made mine out of 090 aluminum without the slot, I think that was an easy way to replace the original taillight, if I had my truck here I could take a pic, Only the old timers would see the difference.
Info only

Not being a smart aleck here, just trace out on cardboard, transfer to similar gauge steel and cut them out.

smog, thats what I did with aluminum and bent it in a sheetmetal break.
A guy could weld, tig, a piece in the slot drill it with a hole saw if you want original. I dont think its a big deal but some guys do.
