CO Looking for Original Acorn Cap Nuts from Factory Round Mirrors

[cericd]

I'm looking for a few original acorn cap nuts which were used to attach the original 67-70 round side view mirror heads. I have my originals but they have been painted over so I'm looking for nice originals that are still the original clear zinc finish, also, not rusted or all nicked up by adjustable wrenches.

All of the nuts I've found online are smooth round (no crown) or high crown which is why I'm looking for originals.

The nuts are 7/16" with 1/4"-28 (fine) threads. Here's a pic of my original (painted gold) nut and a pic I found online to show one in the condition I'm looking for.
