I have a 64.5 mustang 289 automatic D Code w/factory AC that I would like to convert from the Ford power steering assist to the Borgeson. I have replaced the entire system and replaced the eaton pump with one from CarDone, and I refurbished the remote reservoir. It works fine, but of course the control valve leaks. I know, it is a bad design and they all leak. I get it. So I am considering going the Borgeson route. I have a brand new Thompson pump that I plan to use instead of the borgeson pump. I also plan to go ahead and add a one wire alternator while I am at it. So the question is what pulleys do I need to buy that will help me accomplish this? I have factory AC, so I figured I would need a new idler pulley and I know that I have to replace the crankshaft pulley and more than likely the water pump pulley as well. But I can't find anyone that can tell me exactly what I need to purchase. I am thinking this is more than likely a 65 or 66 set up. Can someone help?
