Aluminum bumper brackets, a new offering

My 74 duster had a regular stamped set of front brackets, no shock absorber, just a second bumper (big piece of steel right behind the bumper) if you remove the 2nd bumper the stamped brackets fit. The rear on a 74 duster has the shock set up which I cut up to lighten and suck the bumper in. No way to do an aluminum rear mount that I can see.

If you can post a picture of your duster front bracket I can probably ID it
