I did this just yesterday. I tried to remove the crankshaft pulleys from both of my engines to swap with each other, but found that I didn't have the correct puller to get the pulleys off. I instead checked RockAuto for alternators, and found a price, then called my local NAPA whse/store. NAPA's price was only $1 more, in stock, and included the same pully as the newer engine going into the car, PLUS a special weekend only 25% discount for AAA members--- SCORE!!!!
