BBmonte you need same set up that I do,2-groove crank pulley,1-groove power/str pump witch you have,1-groove waterpump for altenater only.you can't run power/str pump on water pump,you will burn up your bearings and seal's on your water pump.Altenater should line up ok with pulley on water pump,but you may have to make a new power/str pump bracket so it lines up with crank pulley or you can look at some product's by (MARCH Performance) that Bracket is $100.00 and some change.I should have asked this already but i didn't sorry what type of system you running? V-Belt or Serpentine.
