I need to service the throttle controls - lubricate, etc and replace the bit of wood they're mounted on - well, were mounted on, which is why I need to replace it!
I had the same problem - though mine is a Volvo cover (as might yours, but mine is a slightly different design (same but different). I used a screw driver to prise one side out, or it might have been in, and then it pops off. the lugs retaining it are not large.
I too was apprehensive.
Of course once you get inside - the real fun starts. The inside is a marvel of complexity.
