A second gen PS pump on a long water pump crank pulley would put the PS belt on the second groove. The second gen pulleys are deeper groove than low perf first gen pulleys, and the first groove next to the damper is not there on a second gen. The fist groove is needed for the alternator on a short pump setup.
I strongly recomend using deep groove pulleys if possible. Most first gen's have problems keeping alt belts from throwing with the low perf pulleys, unless they are very well lined up.
You can use a shallow groove PS pump pulley with deep groove crank pulleys, the short belt won't want to come off at high rpm's, but the deep groove pulleys are wider and the third groove will be farther forward than the low perf pulley stack, requiring the ps pump to be shimmed forward.
Using a 69 up long water pump and pulleys is a better deal. Just get a two groove crank pulley, a water pump pulley, and use the pickup truck ps pump you showed in the photo.
