hello, I recently bought a 1983 club car golf cart, and I need to know exactly what parts I may need, it came with an easy go charger the crows feet 2 prong type, as this is the same kind of receptacle on the cart.. The problem is, on the receptacle on the cart, the positive battery hole seems to have two prong type things blocking the plug from inserting properly any advice you can give me and suggest what parts I need if any at all, thanks so much for your help on this matter, toby
