Pull the wheel off, cover the steering column, levers/toggles etc. with a rag.

With a small philips, remove the two screws at the top of the cluster. Lean down and look up, you'll see a metal tag with the two screws.

Now is the only semi-tricky part. Tilt the cluster gently forward and shimmy it out far enough to remove the wire harnesses from behind. Now, keep pulling it forward/down to squeeze it out of its confines.

Flip it over to find a plethora of little bits. I didn't change any bulbs, so cannot provide any input, except for the link below, which may help with part numbers.

Good Luck
Many thanks for the responses. The Dave, parts diagram and Shogun's photos are really very helpful. Thanks also to Lorcet, I'll see how I get on. Nice to know there is help out there!
