Yes, you are on the right track and it should be as simple as swapping the single groove inner crank pulley out for the two groove inner and then reinstalling the outer p/s add on. If working with an OE style swp (LH/drivers side alternator) bracket/pulley setup, what year is your setup, are your existing pulleys OE GM pieces and if so do you know any of your pulley p/n's? Had you mentioned needing the crank pulley, we could have added/combined a swp inner two groove crank pulley (OE used $35.) in with Fridays steering column parts order. Don's above added pulley p/n info looks good for small block 72 models, so if you are going to be buying/chasing the above mentioned 3744043 BA two groove inner crank pulley then you should also have the matching short water pump two groove pulley p/n 3995646 AH (see below). Let us know if we can help with any OE swp pulleys, Mel
