Re: Pulley alignment help
For 1972 C/K small block short water pump applications, the single groove outer crank stack/add on pulley for driving the p/s pump would be p/n 3751232BB and the matching single groove pulley on the p/s pump would be p/n 3993325DJ. Here are a few pics of a complete OE power steering changeover removed from a 72 C/2wd S/B 350 truck showing both the matching p/s pump mounting brackets and the mentioned 1232BB and 3325DJ pulleys.

Re: Pulley alignment help
Appreciate all the information. Tightened up the pulley. Had somehow loosened up doing the whole process.
