I am also running a 7 bladed fan, factory shroud, and a clutch! I had all of the pieces on hand, I just put them together!! I recently made another identical fan for a member here, but had to mill out the center for the clutch, whereas mine was already done for that!! Of course, now I'm keeping an eye out for the 7 bladed fans either already milled or millable! If it has a center with round holes, it can be milled for the clutch, if it has slotted holes, not going to happen!!
