The Ford base part number is 7C008 which in the 75 Ford Car Parts says - "improvise". I've ordered a couple from NPD under their stock number 7C008-1. The one I have (still in the bag) was made by Shafer's Classic Reproductions Inc
https://www.shafersclassic.com/ The bracket works which is what I wanted. How accurate remains to be seen.

My NPD version looks close to Brian's pictures, but is missing the plastic/rubber insulation around the hook.
Upon further review (tis the season), I found the original I took off my "K" Fastback AT and it is shaped like the reproduction, but without the insulation. I've use black "Plasti Dip" (Home Depot) to build up the insulation on the bracket (and wiring clips too).
