There are four stamped nuts that hold the speedometer to the dash.

I think they are 5/16, The studs they run on (which are part of the dash) are kinda long. I usually use a 'nut driver' to break the nuts loose. After I get them backed out a little, I can usually use my finger to spin them the rest of the way off.

They are located at 2 0'clock, 4 0'clock, 8 0'clock, 10 0'clock

It is a royal pain to do,

If you do take the dash loose, I would suggest only pulling it out a few inches (I would rather deal with the tight pain I mentioned first, than to compound things by taking the dash loose!)

A hand mirror and lighting behind the dash, may help in doing the task.

Normally when there is a temperature gauge problem, the fuel gauge, which has the constant voltage regulator (CVR) built into it, [this provides about five volts to operate both the fuel and temperature gauges] Is usually presenting problems also.

So

If the fuel gauge works fine, either the temperature sender is bad/or disconnected (purple wire on cylinder head). Seldom have I seen a bad temperature gauge. (They usually barely move, may be mistaken for being bad)

Most of the time it is the fuel gauge presenting the problem, which affects both.

You can test the gauge by taking the purple wire off of the sending unit, stick a nail inside the connector and ground it to a good ground (you can use a alligator clip jumper wire too)

While it is grounded, the gauge's needle will sweep to full hot, confirming the gauge is okay.

Let me know what you find.

Or any more questions.

Oh yeah!

Key must be 'on' for the gauge test.

Just confirmed they are 3/8 nuts, not 5/16.

If they become too hard to spin off with your fingers, you can use a socket (without the ratchet) or even slide a short piece of vacuum line/ fuel line/rubber tubing over the 3/8 socket so that you have something to grip onto while removing the nuts.

Keep us informed.

I appreciate the information on the gauges. I sure it will prove helpful. But, my question was how do I remove the dash with a dash pad? Thanks for your response?

Unscrew your windshield knobs and lay your windshield down.

There are tabs screwed down to the tub (under the windshield) that hold the pad on.

There are also four screws that hold the pad onto the front of the dash, two on the passenger side and two on the driver's side.

This might help if you have some stubborn torx bolts. See my link and pics below. Before you really get on one hard (may break your bit off) Try my technique.

Keep us posted on progress!

See-uns how I have done threw all of my torx bolts into the woods, I had to demonstrate with a allen bolt in my pics. Also you wanna hold good pressure on the torx with the vise grips while you tap the torx socket with the hammer. I only had 2 hands in the pic, So I held the hammer and the camera!
