Hi all, can you please assist re selecting the correct Fan Clutch for my 67 GT 390 Mustang. It will have fitted the 3 Core original Radiator, Fan Shroud and the 7 Blade Fan but without A/C. In order to get the maximum amount of cooling and get the fan as close to the radiator as possible, which Fan clutch do I select? The choices it seems are, C8OE-A, C8OE-B, C8OE-C, C8OE-D
thanks
