I recently got one of my gear shift plunger knobs made and painted the recessed sections green to blend in with the Creech theme since the idea is you are going to the drive in.
The knob is a nice size and really comfortable and all you need is to order from shapeways and then get a plunger rod from Pinball Life and epoxy glue in place.
