Not sure if I missed this but, I know there is/was a "green back belt for the supercharger - the outer belt", or secondary drive belt. Factory belts were (Ford 2R3Z-8620-BC) (Motorcraft JK8-755), the stock part numbers. The Gates and others come in many sizes depending on the pulley setup. Now the hard part, there is also a second belt, "the inner belt, for use with A/C compressor and such. This belt (harder to get to), is also called the primary drive belt, (Ford 2R3Z-8620-AC) (Motorcraft JK6-966A). So what would the Gates green belt be for this one, the inner belt? Thanks for the understanding.
Fred.
