If you mean the instrument panel with speedometer, etc., it is easy to remove. Need two 6-12 inch wires (coathanger works) bent to an L. Insert at about 4 and 6 o'clock, twist so the L's catch the back of the instrument panel, and slowly pull out. It is just friction fitted and the instrument panel has two reinforced slots at the 4 and 6 o'clock areas for removing the panel.
See this from my '81 300SD: you can see the slots
