Hello Katie, from what i understand, regret not, be prepared for quite a battle. Have a search on here for advice and there are some excellent pictures in the Tech Manual, best description i found was here, posted by JA, but other owners may have other methods. Once the instrument panel is out i would test all lamps using a 12V supply before you reassemble, don't want to have to do all of this twice. Take a LOT of care removing the capillary tube and oil line, and don't start the car when the oil line is out

Here is the sequence I always use in removing the instruments;
Remove the steering wheel, it comes of easily and makes the job so much easier. No puller required, just pop the center pad off and use a 22mm socket with extension to remove the nut. Note the slash mark on the end of the steering column, this indexes the installation position of the steering wheel during re-assembly. Next remove the cardboard dash under panel and the upholstered lower dash panel (three Phillips screws). Next remove the electrical plug terminal bracket by unfastening the two phillips screws and move it out of the way. Reach you hand up through the new opening and pull the small defroster vent tube off and out of the way. Unscrew the tachometer cable. Unscrew the thumbscrew holding the tachometer in place. Remove the tach after popping out the two light bulb assemblies. After the tach is removed you have easy access to the thumbscrews holding the center cluster in place. You will need to unfasten the 10mm oil pressure line before removing the center cluster from the dash. The temperature gauge line is not a wire but a small capillary tube. Handle it with care. If the tube is crimped or broken the gauge will no longer function. To continue, remove the small slotted screw at the top back of the cluster. This will allow you to remove the back of the center cluster and you will be able to unfasten the temp gauge and leave it connected in the dash. Be careful when you re-install this, if you do not have the shaft for the dimmer lined up with the knob you can break the glass when you tighten down the slotted screw. Check the dimmer and treat it with some contact cleaner and lube (radio shack) while you have this out. At this point you have easy access to the speedometer and ignition switch if you they need service.
Be sure not to srart the engine while the oil pressure gauge is disconnected, you and your pagoda will get an oil bath! During re-assembly pay attention that the brown ground wire with the ring terminal is placed under the tachometer and speedometer thumbscrews before installation of their brackets, or their lights will not work. Check the lighting before you put everything back together!
