I just put in a 100 amp alternator from Summit racing. Black powder coat. 89.99 outright and no core charge. Also avail in chrome. This is a one wire unit. No bulbs to worry about but you sacrifice the idiot light. Installation required the removal of approx 3/4 of an inch of the back side of alternator pivot casting. Easily carved away with a hack saw. It's soft aluminum and easy to work. Wrap the unit in tape to avoid filling it with metal. Only other mod was the use of the Mr. Gasket chrome alternator bracket from a 350 Chevy. $12.00 at Autozone. Cut it to length, and offset it 3/4 of an inch towards the front of the car with spacers to a small fabricated 1/4 inch thick alum bracket that goes to the original bracket pivot stud on the engine. Bracket goes to the back side of the alt, not the front ala GM. While you're at it, take a look at how the alternator wires get back to the coil/connector box. They must have been drunk....
