glpage.....sorry to take so long to reply, I've been kind of busy this spring. As was mentioned in another thread, the best way to get the gauges out is by removing the upper dash panel for access to the cluster. Here is how it is done.
1. disconnect the battery (some of those wires are hot even with the ignition switch off)
2. remove the garnish moldings on the "A" pillar on each side
3. remove the end fillers on each side of dash
4. remove the screws holding the two chrome trim strips under the leading edge of dash
5. remove the screws under these strips holding the upper dash to the lower
6. remove the four screws at the base of the windshield
7. carefully lift the upper dash panel up and back
8. unscrew the speedometer cable from the back of the cluster
9. remove and label all the wires and bulbs going into the cluster
10 place a towel over the steering column to avoid scratches
11 remove two nuts holding "dogbone" shaped clamps (3/8"?)
12 remove cluster
13 remove the gauge
I don't remember if you can get the gauge out from the back of the cluster, or you have to take the cluster apart and remove it from the front, but it will be evident once the cluster is out......John
