I just modified the existing shifter by cutting 2" off the end and rethreading it. This is the poor man's short shifter kit and since I am now unemployed, I qualify. I also shortened the reverse lockout mechanism so that it would work on the shortened shifter. The main reasons I kept the lockout was that it helps in the 5 to 4 downshift and it looks like this car will eventually become my wifes. The feel is improved and noticibly shorter throws. One thing to note is the thread is metric (M12x1.25) not standard 1/2x20 as I've seen mentioned. If anyone wants more details let me know.
