I'm collecting parts for my 88 c1500 5.7 rebuild. I'm replacing pretty much everything which means I need a pulley for the new power steering pump. The truck has no a/c which means it uses a 4 rib serpentine belt. I have looked everywhere for a new 4 groove power steering pump pulley and apparently they haven't been made for about 15 years. Does anyone have a line on a used one? If I can't find one will the 6 groove pulley work or will it just shred the belt? Anyone have any experience with this?

I was is the exact same boat 2 months ago. My pulley has a wobble, the pump is puking out of the front seal. I needed to replace both on my field truck.
The "yard service only" truck, not road legal anymore, "dont want to spend a dime on it" type of truck... and like an id10t I did an oil change with 5/40 full synthetic, so it can sit in my back 40 for the winter.

You're right, the 4 rib is nearly impossible to find as they were only used a couple years and discontinued.
I found a used pump and pulley on ebay for $65 with shipping.
