Cuban,

Those are exactly what you want for your build date 10/70 Z. There are two versions of this design; one with fewer, widely spaced teeth and the valve stem hole centered in a spoke, and one with close teeth spacing with the valve stem hole centered between the spokes. The fewer, widely spaced teeth design is very early and did not provide a very tight fit to the wheel. They had a tendency to fall off. The revised design with increased, closely spaced teeth hold the wheel better. The valve stem hole isn't in any relation to the 'D'. If you don't like that they are "upside down", take the 'Ds' off and rotate them.

Thanks for the response 26th. So a 10/70 car definitely would have gotten these? From what I've read on here and other threads and webpages it sounded like it might have been the early ones. I just want to make sure I get the right ones!
