The only short throw you're going to get is if you cut down your stock shifter. I did it, and I love it. I took about 2-3 inches off that puppy. All it takes is a hacksaw (although a dremmel is ownage here) and a die to re-thread the end of it.
To get rid of the lock out, you have to pull the lockout cable up and secure it in some way, so that basicly, its like the lockout is always pulled up. I used the dremmel to cut a slit down the shifter shaft and wedge it in there, then used zip ties to keep it in place. Screwed on my knob and bingo!
