Craig, I am just guessing here... Don't the 'Shelbys' had a straight shank (Mag Style) nut with a washer just below the hex? http://www.mcgard.com/custserv/tech_support.asp You may need to buy a set of lug nuts which are the right thread pitch then machine them to length so that they tighten down properly. There are different lug nut washers. I would NOT use a spacer if I could avoid it. You have a set of rims which are dimensionally correct and do not rub on your car when the wheel mount flange is against the rotor face. I know I went through this with a friend that had an older set of Saab rims a couple years ago. I think we found something at Jegs, IIRC. By the way, 114.3mm is exactly 4.5in... Determine the stud diameter and pitch (12mm x 1.25mm?) and desired shank depth and see what Jegs and Summitt have. good luck, Keith Craig's Saab C900 Site wrote: > Hi everyone, > > I've been having problems finding lugnuts the right length to use with the > Shelby wheels fitted to my 1983 900S.
