<html>I bought the high speed pulley from npd, in the hipo mustang section, it fit right on the stock generator and lined up just fine, later up graded to alternator and used the same pulley..The off set issue on the tiger is governed by the water pump pulley flange placement, no issues with cooling or electrical power out put, car has 3:54 gears in the rear, clyde<br><br>Sent from my Verizon 4G LTE Smartphone</html>
