You simply need (hold the pulley) and remove like 3 10 millimeter bolts. There are several teqhniques. You can place a pry bar behind the pulley or pry down on the drive belt just to add some additional force to hold it from spinning. It's best to try and remove it while the the drive belt is still on to provide aditional holding power. The bolts are not that tight and there is no real teqhnique accept using a special tool designed to hold the pulley @ the bolts. Basicaly be creative, it will not take much holding force to remove the bolts and doing the final tightening with the serpentine belt on should be suffcient force.
Try simply pushing down on the drive belt with your hand or prying down on the drive belt for additional force to loosen the bols and same for reinstall just add some additional force. It's far easier with air tools if you have an air compressor and air ratchet before the drive belt is removed.
Yes there are two different versions, sorry my friend. I am not sure what state you are in but contact like AutoZone or Oriely's and ask them if they have a FORD power steering pulley remover/installer 211-185 it's very common and most likely pretty inexpensive. Unfornuately that is the only method possible to install this type of pulley.
TOOL NUMBER > 211-185
If worse comes to worse OTC offers one http://fordspecialtools.com/Detail.aspx?id=685&cid=12
You have a Merry X-Mas and please forgive me, unusal but two different versions of the 3.0 Litre..
