Unique built the Cobra for Goldberg. I was there a few years ago when the chassis was sitting there with a fresh Ernie Elliot dry sump motor almost ready for the body. Bet they know how to get in touch with him.
Jesse James owns West Coast Choppers I believe. I watched a couple of shows about his custom bikes on Discovery I believe. Maybe someone can just call his shop and catch him there. Or
