One thing to add: Regarding the US Indy mag, I bought my 1970 Series 1 240Z from the original owner. I don't know if he had these wheels installed from the dealer or shortly after, but they have been on the car since the early 70's... They are definately 14x7. Ansen Sprint wheels are still made by American (chinese) Racing Equipment. I've personally inspected a 17x8 ansen sprint and it was EXTREMELY light for a wheel of that size.
