Depends on how adjustable you want it to be, I guess. I'd have a trip to some place like IKEA to see if there's any sort of cheap box that can be cut with the jigsaw to be sandwiched underneath the steering wheel, with another portion cut and stuck to one side to hold the shift lever. If you look at rally cars the gear shift is usually pretty high up near the steering wheel, to keep the pilot's hands on the wheel as much as possible. I recognize that keyboard, good catch! they don't make them anymore, I think.
