Those look like Motor Wheel Spyders. Aftermarket from back in the day. I've seen nice examples with pretty hefty price tags. Size, lug pattern, backspace will tell you what they'll fit. https://www.hemmings.com/blog/article/motor-wheels-spyder/
...or you can machine down some ET nuts that have the same profile but a longer shank.
(note that you are removing the protective chrome plating from the end that contacts the drum/hub)
Thank you every one who responded. I am new and have received nothing but support, learning a lot. I appreciate all the support and feedback. Even the little jokes that roll in! :thankyou:
