Do you have a power steering pump pulley with two grooves? Usually, there's a belt for Alt, Water Pump, Crank... then a belt for Power Steering and Crank... as well as a belt for AC, Water Pump, Power Steering, and Crank.

The donor truck had a power steering pump pulley with 2 grooves, so i swapped it out as well. I think im only missing the triple groove crank pulley which is on its way. The only thing im not sure of is if the donor truck had an air pump, so im not sure if all my belts are correct, but your info helps alot. Thanks very much! Also I bought the crank pulley that has all three grooves the same diameter 6.6" does this sound correct? Thanks again

Don't worry about the smog pump, it had it's own belt that was driven off yet another groove (but smaller) on the water pump pulley. Having a smog pump doesn't change how the other belts are routed

Does the alt/wp/crank pump belt go around all 3 like a big oval? Trying to install mine on my 78 350
