Have a old 1985 3.0 with a slow starter. Took it apart, The case had loosened just a bit,needs a new end cap bushing. Fields not rubbed, armature clean and smooth. In the process of trying to find a bushing and brushes I see complete new starters for as little as 75 bucks all the way up to $300. For 75 bucks delivered new why rebuild? Anybody had any experiance with these low $ starters?
