My 04 g35 came without a shift knob. I went to the junkyard and removed 2 from 2 different cars. I can't seem to find a video on youtube on how to install either of them. It doesn't appear to be that complicated but I've yet to figure it out so I've been driving without one. I can't get the push button to work with the knob or it won't go all the way down like they were on the cars at the yard.
