I have a 1972 FJ40 and I am having a little trouble with the belt setup on it. My alternator is on the passenger side of the motor and I believe that there used to be a air pump located on the drivers side of the block. Right now I am having to run a belt straight from my crank pulley to the water pump. What I'd like to know is there a idler pulley setup that I can run to get proper tension on my belt going from the crank to the water pump? The alternator belt is fine because the factory bracket has adjustment in it.
