A custom gearshift you can make for your vehicle. I make these for custom cars since I am a gearhead that loves building cars. I even threw one on my little truck just for grins. They are roughly 4" high by 3" wide. I am sure you can use your imagination and use whatever for the shift knob if you want to. Hmmmm, the possibilities.
Purchase cheesey plastic 8 ball gearshift to use for parts. Approximately $9.99 at your local auto parts store. I am sure if you look at the base of others you may be able to use them-just look carefully before buying.
