Pulley Diameters

All belts and accessories are now lined up except for the alternator. I think if we replace the single alternator pulley with a dual pulley, the last piece of the puzzle will fall in place....

From doing some research, the pulley change over is not a piece of cake :BangHead:

We have a puller to get the pulley off, but not sure about installing the new one. Words of advice??
