My pulleys are not aligned.

thank you from Germany

Crank pulley is a 3 groove pulley, waterpump pulley is a 2 groove pulley.
Crank pulley groove by engine routes to waterpump(innergroove) and then to the alternator.
Middle crank pulley groove routes to the waterpump(outer groove) and then to the AC compressor.
Crank pulley outer groove routes to the Power Steering pump.

Ok, the WP bolts on mine measure as follows,

Passenger side top 2 3/4 inches,
Passenger side bottom 3 1/2 inches,
Driver side top 1 5/8 inches,
Driver side bottom 1 5/8 inches. This one has a fine thread stud on the head which wasn't being used. Stud length is 5/8 inch.

This is on a 72 with air and power steering. Can't guarantee these are original because i didn't get the truck until 1998.

You're awesome! Thanks! This confirms my thoughts. I was missing the passenger top water pump bolt and was attempting to use the front passenger intake bolt which holds down the a/c bracket. Either way i would have been short a bolt.

I found my missing wp bolt hiding in the frame carriage in a ton of gunk. This truck needs a serious power washing underneath after i get it back together.
