Then you will have to remove the wp rear cover and press the hub down the required distance with the the back of the shaft held in the press. The pulley just needs to go on further so the ac belt can ride in the outer water pump groove,to the second crank pulley groove, and over ac compressor.
Hey Mark, any pics of your 16K 74, those trucks are killer.
