Looks like a Mopar part number and from the sequence I would guess 66-68. No pentastar?
Likely its aftermarket....similar to Hayden. Thr giveaway is the slotted mounting bolt holes....Mopar clutches used drilled mounting holes. The fins on the body are more shallow than Mopar units. Just my opinion of course.Sorting out parts for Carlisle. Came across this fan clutch, hands lots of makes and models over the years . Tried searching the ink stamped number came up empty. Is this a Mopar piece or just an aftermarket clutch?
