speedo removal

[TireFryer]

I have never done this before, but I need to send in my speedo unit to get recalibrated (the needle got banged or loosened or something first time around...with engine off, it stays @ 25mph!). If someone could post a step by step on how to take out the speedo, from A-Z (including dash removal, screws, wires, ...?), I would really appreciate it
Thanx a bunch in advance!
