Hi Alfredo, I just sent you a Email
I've seen old Shelby wheel's (70's era) like these before, but never with a spline drive? Are they a true spline drive or a fabrication from 4-5 bolt wheel? Shelby made many garden variety (Read: Cheaper) wheel's back in the 70's-80's, many copied from higher end wheel's. Send me photo's of the back side, K? Width? Dia? Cheers Tom. I had a copied set of American Racing Libre's (Shelby Viper) for my Z-car, they turned out to be much rarer then the true American Racing wheel's.
