Ah, that totally explains it -- there's a groove in the water pump pulley to match it!

Now I need two pulleys

I just posted a thread on P/S & A/C. It shows you the pulley set up with only 2 pulleys. I am working on different combo's of pulleys now will keep you informed. John

Hi there, bpmcgee.
Did you ever get your pulley situation worked out? I'm in a similar situation. I found a 2 groove crank pulley in a junkyard...but I don't have anything to match it up with?
