If any of you find that the stock lug studs on your Corvette hubs are too short for your wheels as I did, the only source of long lug studs that I found was a fellow named Jerry McKinney who is the parts manager at Lawrence Chevrolet which I believe is in Harrisburg, PA. Jerry is very much into roadracing Corvettes which is why he carries these longer studs. He can be reached at 800-427-4505 or 717-766-0284.
