Ok, so my new TKO 500 will be here tomorrow. It comes from the factory with a short throw shifter, but it has no handle. My question is, does anyone know what kind of handle will fit the shifter base?! I've been trying to call tremec all day, and their customer service absolutely blows. Are they all the same, hadle wise, or are there variations? I'm gonna go insane if these ****ers don't pick up their phone!
