Please use my email address for questions or to buy these parts as I just can't keep up with who is who using PMs and email, and eventually we have to get to email if you buy. The names rarely line up and I try to do first in first out when more than one guy is interested in the same part. smshirk at bellsouth dot net.

For questions on spacers there is an album dedicated to wheels, spacers, and center caps. Each pair of spacers is pictured with size and price in the remarks on the first picture of a particular spacer. I think I have 5 or 6 pairs from 12 to 25mm. All are hub centric. All but one require longer bolts, where that one set at 20mm have separate lugs and nuts included.
