Try to get a hold of "Beans" he is up around Claremore. He may have someone for you to contact for used parts and he is pretty good for advice on these older engines as well. He is a Notebooker but he works full time and has a very busy schedule. You may want to ask for him to Email or call you on the regular "Message Board" forum as well.
