John-
Did that alternator pulley you sold Jon come in March's 3 piece set? I have
the Performance Pulley Set #10510 which comes with an alternator pulley that
is bigger than the stock pulley. I wonder if the other set, Power And Amp
Pulley Set #10515 comes with an alternator pulley that is smaller than the
stock pulley? Any insight you may have will be very helpful.
Thanks!
James

As a matter of fact, I think the smaller diameter March pulley that I sold
Jon Steiger was for a Jeep Grand Cherokee.
