AC power steering pulley

Okay I think I am going to try and piece together air conditioning on the 79. Do all AC trucks have a double groove pulley on the power steering pump? I am going to use a sander compressor

Re: AC power steering pulley

My 83 305 did. My other squares have straight 6s in them, but they do not, but probably doesn't apply

Re: AC power steering pulley

My 81 is double. Might be a case of the belt not clearing a single power steering pulley, or maybe not clearing the power steering shaft if it goes direct to the crank.
Old picture, so not the best angle.
