Reproduction 58-74 Big Block and 70-88 Small Block Single Groove Crankshaft Drive Pulley for Vehicles without A/C, without Leece Neville Alternator-found mostly on Police Vehicles, and without Power Steering. One of the Bolt Holes, (As seen in the Picture Above), on this Pulley has been Elongated so that it will not only Bolt onto the the earlier 58-71 Big Blocks and 70-71 Small Blocks with the offset Bolt pattern on the Harmonic Balancers, but will also Bolt onto the 1972 and later Symmetrical/Even Bolt Pattern that the Factory started to use by then on the Balancers. The Factory only used Single Groove Crank Drive Pulleys until the end of 1974 on Passenger Vehicles and well into the 80's on Trucks and Vans, after which they only installed 2 Groove Pulleys, even if you had Manual Steering without A/C. The Diameter of this Pulley is approx. 6-1/2". Will NOT work on the 426 Hemi's. Replaces OEM Part #'s 1821449, 3614375, 3671319, and 3769134.
