PS pump pulley
 

I have a 327 out of a medium duty truck, and it has a deep groove 3 row crank pulley, GM part # 3867176. Does anyone know what PS pump pulley matches this crank pulley? I am using PS pump bracket 3957466.

If no one knows which PS pulley matches 3867176, does anyone know if pulley #3873847 is the deep groove version of #3925537? It is the correct off-set, but it is not deep groove.
