I went to fry's yesterday, and picked up some wire, soldering iron, solder and a 500K pot. (500k was the closest they had. the others were 10k, 5k, 1k)
I clipped the wires on the old pot, and soldered in the new 500K pot.
It works! But, the volume is weird. It can't be turned all the way down (off). And it almost seems to have more gain.
At any rate, it works, and will be good temporarily until I get my new wiring kit. The cool thing is that the pot was only 2 bucks!
I'll post pics and an update when I re-do the wiring the right way!
