I had heard through the grapevine, so I don't know if it is true or not, that Steve Blake would have small manufacturers of wheels, do one off sets, telling them that if he liked them, he would buy a bunch for his cars. I suspect that is the case, on my 1985 Convertible, as I have also not been able to find others just like them. And I have one non-repairable wheel. so I switched to wire ones, which I do not like as much.
