Along the right side of the instrument cluster, you will see four screws. it's pretty dark in there; you may want to do this by feel.

Two of the screws hold in the right side of the instrument cluster; don't bother those. You will feel two "feet" that come from the bezel that is over the CRT; take those two screws out. There are two clips on the right side of the CRT bezel; just carefully slide a thin flat blade screwdriver under the right side of the bezel, and it will snap right off.
