I've been looking into this recently, as I have a few original (and
very used) fans lying around. Going by the parts book page above, it does identify which fans were listed for the V6, just in a round-a-bout way. From 1970 the GT was the V6, so up until April 1970 they were allocated a red 6-blade fan. From April 1970 they were allocated an orange 10-blade fan, and the 165hp specials were allocated a different fan again but the parts book doesn't describe it. From a fan I have here with the same part number, the 165hp specials look to have been allocated a white 7-blade fan.
