i have done it about 6 times on different micras, including facelifts with twin airbags etc
i would say it is easy,
lets say you split the dash in half, the screws are mirrored on the other side,
you have one at the top under a little flap, thats the hard one to get at because getting the flap off in the first place is hard,
then you have one on the very side, this is under the door seal rubber, you should see it with the door open
then there is one at the bottom, you will see it if you get under the dash,
another one behind the centre console. to get at that you will have to undo the centre console, (two screws above the stereo, two behind the ash tray then carefully unclip it from the top) you will also have to unscrew the heater controls (4 black screws)
now all of that is mirrored on the other side, but there is still more,
you have to take out the tray from under the steering wheel (two screws) then you have to take off the steering wheel surround, (4 screws on the bottom one of which is under the angle adjustment lever) and take of the indicator stalks, (clips or screws depending on age) then you can take off the guage cluster, (two screws at the bottom NOT the two above the needles)
then take out the cluster (three screws, one at the top two at the bottom) and unplug everything (Squeeze the speedo cable to release) and behind all that you will find the final screw which is on the left hand side behind the cluster,
then, providing you have unplugged everything, it should lift out, obviously taking the steering wheel off too.
it sounds like a lot of work, but i have taken many out in the scrap yard without breaking anything, in 15 min
its about just looking and seeing whats holding it in place, there is nothing hidden,
