Its really easy, pretty much start dismantling the upper dash.
Remove steering wheel
Remove stereo
Pull heater control dials/levers off
Undo screws to upper and lower dash
Remove the switches for lights, fogs etc.
Withdraw the dash facia, then theres 3/4 screws above and below the speedo holding it in
Pull the speedo forward, then with your left hand, stick it behind the gauges and squeeze the clip for the odo and pull it out, be careful the locating pin doesn't fall out.
Reach under the dash and undo the 1/2 electical connectors off the bottom.
Pull the clocks out.
Kinda like this,
