i k ow i dont, pretty mych everything you have said ive added to the car, plys reading alot of your posts helping other people with amp problems. i wouldnt be anywhere near where i am today had you not helped. i read a lot of stuff, but you help make it make sense. that goes a long way. gs sent an email today saying i should get a new alt belt and it should be from.5 to 1.0 inch shorter for the new amp. i sent them an email back and asked them which one they recommend, because i only want to do this once. im kind of dreading having to take out this alternator because of the tension arm and its location. im pretty sure there will be wrenches flying and much knashing of teeth... lol
