the buttons dont latch down, they are one touch and the scu holds the switch on, where as the mark 1 the switch itself holds the switches on.
if you got a suitable red led bulb that should shine through id think, but the clock bulb the glass doesnt come out of the holder, the holder is part of the bulb, the instuments the bulb is seperate to the holder
but the buttons for the aircon, recirculate are the same as the mark one and will fit, the only one you will need to change will be the heated rear screen button
