Just put my new kart boy short throw shifter in my car today. Wasn't hard at all really. Took about an hour or so. I already had the shifter bushings installed.
Let me tell you. There is nooooo play in the shifter now and the throws are 40% shorter than stock. Shifter is about an inch lower. The throws are so rediculiosly short now. Definately a worth while mod for the Suby guys
