I have a set of March aluminum pullies, Power and Amp series number 4410. Water pump pulley has usual belt rub/discoloration and the alternator pulley is NEW. I had to get a new one when my old alternator siezed and took the pulley with it. Balancer pulley has been bead blasted on the inside since the old bolts left rust marks, has some rubber color in the grooves too.
Here is the link to them on Summit's web page
Asking $145 shipped USPS in a flat rate box.
