The CAA pulley is 1 sheave width(~0.5") shallower than the original W/P pulley. That in my opinion is to much offset from crank to alternator to water pump. The rear sheave of the CAA pulley (closest to the engine) lines up perfectly with the A/C compressor. So if I just used the CAA pulley only, every belt minus P/S would be 1 sheave width out of alignment. I do not believe that is acceptable. Correct me if I'm wrong.
Eric thanks for the heads up on the damper being the rear sheave definitely something I need to consider/ research. Good catch on the pulley from the CAA website pictures. I will be calling them shortly.
