A/C cars with/without power steering used the same 4 groove crank pulley.
Part # 2465326 Used in all B and C body B-block ac equipped cars.
440 engines used a different pulley.
The outside groove is for the water pump.
The next groove is for the power steering.The two inside grooves is for the alternator & A/C compressor
Here is a copy of a factory assembly blueprint:
Hope this helps.
Keep in mind that is with the Chrysler alternator.
There is a three groove alternator pulley with the Leese/Neville alternator.
Which alternator you have???
