74 D100 Rear Bumper Brackets

Does anyone here have a picture of the rear bumper brackets for a 74 D100 Stepside?

These two brackets were on my truck. Wondering if they are part of the bracket system for the stock rear bumper

Those kinda look like step bumper brackets. Might find some info here. https://www.bing.com/search?q=74%20...mp;cvid=84C2161345C44518B22C3A501A57F8E7

Here are pictures of the originals on my 78 rear bumper.

Thanks, this pic really helps. Of course those brackets seem to me hard to find.
