single ps belt to dual???

[RootBreaker]

Ok so I tightened my power steering belt... then after a few hours of wheelin it loosened up again.. I was told that the double belt setup is better... how can I get one? what cars, trucks would have it so I can goto the junkyard or aftermarket kit....
thanks

an airconditioned truck will have a 2 groove pulley on the pump, 3 on the crank and 3 on the wanter pump. then you got the 2 belt power steering pump.

you might want to check the brackets to make sure none are cracked, had the same problem and the bracket that bolts to the head and manifold was cracked.

If it's loosening up, somethings not right. Belt should break before you ever have to worry about the pump working itself loose. In ther words, just figure out why it's loosening up and fix that, no need for a second belt.

You'd need a complete pulley setup off of a donor vehicle to get them to line up likely, and power steering pulley is a pain to get off, need to get the puller to remove it. I had to deal with pulleys off of multiple vehicles putting my truck together...it's a major hassle. All sorts of different pulley combinations used, and that means that not all pulleys will line up with each other.
