Pete, is that the burb one? mine doesn't look anything like that. I just ordered one from O'rielly's #4220, the body is just like mine but has a threaded cap/end on it. I took it off and the shaft is different than mine, mine has a worm gear end on it and fits into the head with a large gear on it. The guy is ordering an other one to see if boxed wrong. His book says fits 69-72 I think....
