I'm doing power steering conversion using Saginaw components. I need to get the power steering pump belt, but can't find the specs for it (width and length). I've been reading the forum and seen that many just grabbed few from the store and then return the ones not needed. Many stores here do not stock big variety of the belts and need to order them in. NAPA only accepts by application. Returns are subject of 20% restocking fee. I wouldn't mind to grab 2-3 and then return 1-2, even with such restocking, but with 1/2" increments, do not want to get 10 belts and return most of them. What specs or even application should I look for???
