boy, now I am confused. Typically the 2 groove water pump (wp) is to line up with the two groove crank, like you said. PS lines up with outer crank and alt lines up with inner crank. both across the wp.
your 9778808 wp is for a 65 but is the same pulley as the 64 538547 with PS.
okay, if the wp is supposed to work, then the crank is too far back, but if I move the crank forward to match the wp, both the alt and the PS would be wrong.
but if the crank is supposed to work, then the wp is too far forward, but if I move the wp backward to match the crank, the PS would be right and not the alt based on what you said.
So, what does this mean, since the hub for the balancer has a lip and can only go in so far, cause if it went in too far, the hub would rub on the timing chain cover, so usually the crank pulley is in the right location by default. The wp should work, be sure there is no spacer behind the pulley and the water pump. Measure the height (depth) of the water pump, cause if the water pump shaft was out too far, or the wrong one used on a rebuilt water pump, then the pump hub would be out too far and the pulley would not line up.
Lastly, the 64 alt single groove pulley is universal number used all through till at least 1972 and is very common. If the alternator bracket is correct, that alt if it has the right pulley should line up with the crank. Maybe you also have the wrong alt pulley.
Check the water pump depth, no spacer, what does the alt line up with or how far off is it from the inner crank groove???
