Can someone explain the me the underdrive pulley rules. I'm confused, do they take effect on 1/1/2006. What can we use now, if anything?
Thanks,
Bill

The rule change on 1/1/06 applies only to the crank pulley. The alternator, power steering, water pump, supercharger, A/C, etc., pulleys are already unrestricted.
