You can oval out one hole in the pulley to make it fit the one offset hole that overlaps. Just grind it a little, make sure to use a washer, and you're good to go. :D
Try to line up the holes on the pulley with the ones on the vibration damper/balancer and then you will see which one needs to be "tweaked" and then go a little at a time and test fit it until you get it to clear enough... #-o
Don't let the offset hole be a show-stopper.... :twisted:
