cant get pics, but the back has a regulator box, and a few wires coming out of it. its a single wire.

im looking at summits site for alternators and found what appears to be the exact one i have but with a single groove pulley.

however, it appears that it mounts up like any other alternator summit sells for the 340 plymouth and so i think ill try a summit brand alternator since this thing has approx 250 miles on it before eating itself appart. not very tuff stuff....
