Updating alternator - have a few questions

Thanks guys. Guess this one I have may not be original then. Is there any drawback to having a square-back over a round other than cosmetics?

Also, one of these days, I need to get around to getting one of Crackedback's headlight relay kits... but this needs to be taken care of first :thumbsup:

I don't think it matters as long as the alternator is functional and has the proper amount of field wires for your application...

But if I remember correctly, I once tried to put a square back alternator on a 68 car that originally had a round back, and the square back hit on the engine and could not fit... - that was a draw back...
