It's been a few years since I have had mine off so I'll try and remember for you but it's pretty easy. remove the kick panel from under the steering wheel, it has 2 small bolts on either corner at the bottom holding it on and then pulls off. next remove the collar from around the steering column, there are 2 screws from the underside holding together ( it's in 2 halves). this will gain you access to the lower screw tabs holding the gauge shroud, there are also 2 more on the top side recessed into the shroud. the shroud should lift up enough so you can unplug the headlight & hazard switches. now you have full access to the gauge pod, you'll see the mounting screws holding it in should be 4 if I remember, you will be able to pull it forward enough to reach back there to pop off the speedo...note sometimes it can be a PIA but it will come out.
This is all from memory and pretty accurate ( my car isn't at my house to run down and look at ) but if I'm off on something someone will chime in I'm sure.
