I have a supply of original lugs and nuts in various conditions. Some are usable and some are rather worn on the grooved surface. I bought replacements at the local auto store for my driver 28 Coupe. If you want one of the original usable studs and an acorn nut to do an original restore, let me know. I will give you the stud/nut for free, and you only pay the shipping vis USPS priority mail. I think that is around $6-7.
If yours are not rusted in, I removed mine with some lubricant (rust remover lube), heat from a map torch, and some light blows from a hammer and drift pin. Mine were rusted in on some wheels when I had to replace them.
To avoid confusion, send me a picture or exact specs on what you want. Some of these old cars had different parts at different times in spite of what others might say. I want you to have the right one. Contact me on my personal email at arts28@cbs-inc.com and go to the following website where it is also listed:
