Is it just the instrument binnacle you want to remove? If so easy-peasy... just unscrew the 4 stainless steel "knobs" two at the top and the 2 at the bottom which also serve as the dash light dimmer and trip counter reset.
If it is the whole wooden insert on the dashboard you need to get your hand up behind the bulkhead and feel for the location of several very small (6mm from memory) nuts that retain the chrome strips on the dashboard. Some of these may shear when you try to unscrew so take time and try to soak with WD40 before you start the job. You'll also need to remove the ignition switch, clock, flavia badge, ash tray, air vents etc.
It's not complicated just a bit fiddly as 2 or 3 of the bolts are very close to the steering column with poor access.
Is this the later model. The earlier model is undone from behind.
