I am considering getting a = short-shift kit for my 90 Carat. The first owner did a lot of "tuner" mods, = so there is the chance that I might already have one installed. So I don't = embarass myself by ordering one and then discovering that I already have one, how = can I tell if I have one without crawling under the van? When I am in = 3rd gear, I can place my palm on the knob and still touch the radio with my = outstreched fingers. I am assuming that a short shift kit will change this.
