Wilson 1" Lightweight tapered spacer. Part #004110. Would like to trade it towards a Wilson 2bbl adapter part #044330. Taking a shot here that someone might be moving up to a 4 bbl. class and has an adapter they can't use anymore. Or, I would sell this outright for $85 (+) shipping. For more info, e-mail: fastfred1a@yahoo.com Please put spacer in the subject line. Thanks......
