Easiest way to change an alternator pulley with no special tools?

[BadBlue98GT]

I'm running a 4 pound lower/2.7 upper pulley combo and subsequently switched the stock alternator pulley for a 3.2" Metco a few years ago. Because of a dumbass mistake mentioned in a separate thread, I fried my alternator this weekend and need to replace it. I remember that when I replaced the alternator a few years ago, I had a helluva time swapping the 3.2 pulley out with the stock one the new alternator came with.

Before I attempt this again, is there an easy way to swap the pulleys with no special tools?

this.

On my procharger which I actually torque to spec Ive used a strap wrench to hold the pulley in place.

Impact. Even the cheap electric ones from Harbor Freight can do it. Buy it, use it, return it. I did this on vacation one yr with my car.
