I have recently acquired a set of 4 and3/4 by 5. 16 inch wheels. They were from a S-10 Xtreme. They look really sharp and I was going to mount them on my Chevelle (1970 SS). The lug nuts are Metric,of course, I need 7/16 by 22 lug nuts, with the enlarged acorn head (standard threads).
I have searched the forum and all of the companys listed and no one seems to have what I need. The factory lugs are just steel and are open on the end. Help!

They're not too hard to find. I got mine from Summit Racing. They're not in the catalogue, but if you call they can fix you up. I'd think that just about any wheel manufacturer should be able to supply what you need.

Go to your local Discount Tire. They'll have them in stock.
