Since they are not painted and dont rust my guess is cad plated flat steel was used. They are easy to reproduce from store bought flat stock. I can measure one in the morning.
Ok. Had a loose one on the shelf. Made from 3/4 wide flat stock. They are 6 3/4 from the inside to inside of the number plate. The down legs are 2 inches. The hump where it sits on the fender is not as exaggerated as the picture looks. If you weld the nuts on it will rust where the plating is burned off. I would use 6mm nylocks instead. I get the width and hump right and let the down legs run wild. trim them to 2 inches when done.
3/4” flat stock? Really? Darn! I bought 1/2” flats stock today. Guess I’ll return it for 3/4”!
I have an extra Road Toad frame I’ll use as a guide for the rounding. Tell me, what’s the arc length of the curve? It will help me with the bending.
Thanks, Olddogs, for all you’ve provided so far! I was thinking about drilling and threading the holes for a 6mm threaded bolt. Thread first, screw in bolt, screw on nut and tack weld nut in place. Should be sturdy enough to hold a plastic number plate! Thanks again!!! Victor

If you are going for the full look of the original brackets the nuts were the flat square weld on type. They are unplated and weld on better. I bought a box of them years ago and they have come in handy to have around.
