NO FLACK FROM ME!! I just bought this Jag fan clutch ( Hayden 2765) And couldn't believe how it worked out. You would think all the specs would be Metric, but- My stock Mopar 7 blade fan fit perfect , even the registers in the middle of fan hole, I can even use the stock mopar fan blade bolts! Hayden includes a bushing that will go from the larger Jag water pump down to the Mopar pump. The water pump bolt holes line up with the jag clutch, altho the bolts are near the edge of the slots in the Jag clutch. NO problem. This Jag fan clutch is over 1/4 " narrower in width and leaves lots of fan room from the radiator. I just mocked mine up and possibly the bushing they sent may need to be narrowed slightly. Most people will never be able to tell it is not a stock Mopar clutch. THANKS A GOB!!..................MO
