all ford trucks in our years used the same power steering pump. vans used a different pump. get a pulley from a truck. they are all the same once you get to serpentine.
On the power steering pump, it may be all the same. But on the Vac pump, and the belt tensioner there was some variation in the last few years. I've learned that the hard way, and I'm still learning it. Apparently for part of 93 through the end of production in 94 the used a tensioner with an enclosed spring design, the cost of which is twice that of the older design, and they are not interchangeable. Mine broke on me this morning, and I have the enclosed design. Guess which version nobody keeps on their shelf.....
If your tensioner hasn't broken yet, take a 3/8 ratchet, short extension, T50 Torx bit, and a 13mm socket with you to the P&P and grab you a tensioner assembly while you are at it. Mine is coming from Rock Auto for a total of $76. To buy one locally the costs range from $96 to $120 plus tax, and 80% of the time they will still have to order it.
Oh, and take a good magnet with you so that when you drop your tools into the fan shroud you can pull them back out again easily. I used a flashlight and small mirror to see what kind of bolt my tensioner assembly was held on with. Apparently some use a T50, and some use a 13mm. Some probably use an Imperial size as well.
