Hello all, I am in the process of rebuilding a 1956 Oldsmobile 324 engine with power steering and A/C. The A/C compressor and generator have the double v-belt drive and the generator kindly came without the pulley. Anyone know the Original GM Part # for the pulley? Or in the worst case know the outer diameter of the generator pulley if I have to machine one myself (or where I could buy one)? Thanks in advance.

A standard 2 groove pulley fits a ton of years both generator and alternators.

Can buy at most any parts house.

Looks like 1929969.
