I made an aluminum base plate based on DustyB's picture provided. Thanks again DustyB! I used an old scrap speed limit sign I had and cut it out of that. Believe it or not, I was able to find locally, NOS 10-32 Palnuts. It was an all or none purchase so now I have around 80-100 of these... I was not able to find any feet that were close to original so I decided to use what I had, and since I have extra Palnuts, I used them as fasteners on the feet as well. Not correct as original, but it all matches nicely and I think it looks good...
