the way poppasmurfs is set up, you will have to remove the fan shroud. make your own bracket, weld a v belt pully to the alternator pully, and make your own tensioner pully. good luck.
 I had a York 210 mounted off my alternator on my 01 f150 with the V6.Iwish i could find some pics of it before i took the cab off, but i had to bend an AC line out of the way and reroute the upper radiator hose. Kept A/C and all that good stuff.
