Dan,
I ordered the alternator kit from replicaparts.com and kept the reverse rotation water pump.All you need to get is a fan belt that is a metre long(Bosch 6pk1000).The alternator kit was $75.00us.Not much contact on the pulley but 3000kms and no slippage at all.Saves alot of space not having the serpentine pulleys there.
Cheers
Brett
