don@transmissionclinic.comHe actually has a fully restored EB with some kind of a huge engine in it I think. He has done some work for me in the past and I'd say he does very good work but is not cheap. You can tell him that I (John Papp) sent you his way -- he is usually pretty good about making deals.
