I hope that was a joke... Not trying to be an ass, but the point of a short shifter is to shorten the throw - that has to do with the design of the shifter.

Cutting your stock shifter will actually make your throw longer and worsen the situation.

But anyways, its really easy to do. The first time I did it, it took about 30min. Basically, what you're doing is taking the shifter apart from the shift linkage (which goes to the transmission) and simply replacing it. B&M makes half decent shifters which can be found relatively cheap. I've heard a lot of stories about ebay shifters snapping, so I wouldn't recommend shopping for one there.

The bottom of the shifter that connects to the shift linkage is outlined by the yellow circle in the first picture:
