My pulley arrived today. After an evening with some friends (watching Gladiator and drinking a couple beers), once they left, I ended up starting the project at 1:00 AM. It only took me about 1 hour 40 minutes thanks to sd_boxster.
The only thing I did differently was to use a screw driver head instead of his leverage contraption. I put the screw head through a hole in the stock pulley, and into the boss (see pics). This held the stock pulley in place while I loosened it.
