With the recent interest in these fans, I dusted off the one i had book marked for my 67 L78 Camaro, its different from the "$1,600" fan in that it has 5 flat rivots, the fan blades seem to be flater than most others i've seen and its stamped with the #'s "89" (last two of the part # ??). It does have the 3 1/4 bolt hole spacing and is 18 inches in diameter and has the deep pitch (side of the blade measures 2 1/8 inches when laying on a flat surface). One person i have ran this by says its for 1968, 4 rivot for 67....any input on its true ID ?
