Dave mentioned wheel spacers. Sean made up a batch of custom spacers at someone's request. I think they are 1/16th. If you need to do some minor tweaking they are available. They can be stacked. Cheap. Of course we have them in .250, too. Joe Alexander 645 1st Street Jesup, IA 50648 The-vintage-racer.com Gasketinnovations.com Cell: 319.464.4711
