desert, the pulleys you show are for an ac truck. mine is a non ac truck.
my power steering belt is on the crank and water pump. I physically dont have the last groove that you have in your pictures.
I am going to convert over to the ac style pulleys in order to use the belts as gm intended.

The compressor is fixed in its forward and backward position. can not move it. its fastened to the cylinder head basically.

I have the top left non ac one ton small block set. Why there are four different belt setups for 91 is beyond me.
