Year: 1996? I think

Mini Cooper - Speedometer just stopped working. DAMN >

We have recently bought a MiniCooper, it's the classic style not a BMW mini (I thinks its a MK5).
It's been great since we had it, but for some reason the speedometer just suddenly stopped working.
I doubt it's a major problem but i'm not at all familiar with these cars (yet!).
I guess that it's either the sppedo guage or maybe the speedo cable but i've no idea how to remove
the speedo cable (engine side) or how to remove the clocks (dashboard side)

If anyone can give me some simple pointers on how to remove the clocks and any other
points that may help me fix the problem it would be a great help.
Cheers
