			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?  |

			I understand this is an old thread...but Does anyone have a picture of the double pulley...I haven't been able to see a quality picture of what I need.  Thanks!
