Thanks John--I think I have those now----I bought the oem Truck BB accessories and pulley's when I did the switch to my 502. I looked at it today again and the PS pulley is slightly warped---it wobbles just a tad....maybe time for a new billet pulley...well then that means other Billet pulleys---then I need to match it with a new pump----then braided lines----crap....I guess I am not going to get lunch for the next month!
