Joe50,
I have a set of March, PowderCoated Black, Underdrive pullies and the alternator pulley that came with this kit is larger than the stock one!

The March pullies have a smaller than stock crank pulley, a larger than stock alternator pulley and and larger than stock water pump pulley!

I went back to the stock pulley on the alternator becuase of charging problems. No problems now unless I'm idling for a long time at night with the headlights on, A/C on and the CD player kicking it out!
