The 1983 t-bird 302 uses the same exact water pump except it is forward rotation. Just transfer the pulley over (pulley needs some minor hole drilling) and have a fwd rotation system. It's what I did.
I took the alt off it's bracket and bolt the tail end into the head using a sleeve (swaybar connecting rod sleeve? Not sure where it came from, it was in my box-o-stangparts) as the spacer. Then I wedged 2 valvesprings inbetween the alternator casing and the WP elbow to tension the belt. Easy simple, lost a whole bunch of weight. The stock system has some really long bolt shaft thingy with threads on either end....think it came from the power steering side....this threads into the head and you drill the alkternator's case so the bolt slips through the original alternator lower bolt position. Then it pivots. You use the belt to pull on it and the springs to push.
