Powerbond UD Pulley Install:
After having a fit getting the old March pulley off (and breaking a harmonic balancer puller bolt off in the pully), I didn't want to take any chances damaging anything else due to questionable hardware.
Not the cheapest bolt (~$27), but I felt better using it.
The greater number of points on the head of the ARP bolt seemed to make tightening somewhat easier.
Good luck.
