To the best of my knowledge there aren't any.
As they are right and left handed they would require 4 molds. If anyone is seriously interested let me know. I'd like to make some in alum. They would probably cost $4,000 a wheel for a small run!
A couple of years ago Fran Kress told me he had some Mk IV "Turbo-Flipster" (as described on the MPC model kit) wheels for sale. Wanted to know if I had any....yeah, right!
Could be worth a try. There are a lot more wheels in existance than you might think, 4 or 5 sets for each Mk IV at each race and I doubt they went with the cars when they were sold. I would bet there is more than one coffee table in a rec room mounted on a rear Mk IV wheel....
The ones that are safe are all accounted for.
35 year old mag is ify unless it was never damaged and properly maintained. I have ten good ones. I looked at Fran's but didn't buy them as they showed too much corrosion for me.
