In another thread I asked wether to polish a few things or not...well, I decided I am going to powder coat like a few suggested. So instead on buying a new $400 chrome alternator, I am going to take the housings off and have them powder coated. The problem is I have the front cover off but the back will not come off. It wiggles as if there is a bolt holding it one but I have taken all the bolts out. How do I get the back cover off? Is there some sorta magnet or something? Please save me $400+. Thanks.
