many people have taken the cubby hole from other vehicles and fit it onto the CD changer brackets so they have a cubby space, i put a head unit with DVD capability in the CD changer slot then put a flip out monitor where the stock cassette player was, but i dont have the auto shifter anymore, i swapped it out for a much much smaller one, so keep in mind that your stock shift knob might get in the way of putting CDs in

other people have put gauges in that area, i was going to put in a switch panel or a DIN sized speaker like the one biju recently sold before i decided (more like couldnt resist) on my DVD setup
