Hey Darren,
Looks like you're off to a great start ! My suggestions, use leds instead of the old bulbs. They will last much longer and be brighter. Tape the chrome parts of the Bezel so they don't get scratched when putting it back in the dash frame. Check the clips in the dash frame and make sure they are not stripped out. If they wont take a screw when you are reassembling, you will end up taking the whole dash apart again to replace them. If the interior is already in the car, take off the steering wheel, and drop the steering wheel column. Also take out the screw that holds the fusebox in place and leave it loose. It will be much easier to install the cluster wiring . I found it easier to connect the headlight switch to the wiring harness and install it after the cluster is in place. Same with the wiper switch. A little modification I made was to replace the screws that hold the heater controls to the cluster with 1/4-20 studs instead. Its much easier to put a nut and washer on the stud instead of trying to thread the screw into the diecast cluster housing to hold the heater controls in place. Before you put the cluster in place, use a 12volt source (old car battery ?) to test all the lights and the gauges.
When reassembling the Bezel, first clean and wax the clear lenses, make sure all the blue light housings are in place and are tight and not leaking light. These blue tubes get quite dirty so clean them well. Also, get a 50watt pencil type soldering iron with a spade type tip. You will need this to melt the tops of the plastic studs when re-assembling the plastic gauge parts. Wherever a screw threads into the circuit board ,and into the diecast cluster housing, make sure to use the star type washers. They cut into the circuit boards to ensure a good connection. Also make sure the dash frame is well grounded , use a test light probe to check it. Should light brightly if the ground is good. Also, if you can find one, get a bezel nut install tool for the nuts that hold in the wiper and headlight switch. Not necessarily needed but its very easy to let a tool slip and gouge your new cluster. I made one with an old deep socket that I grooved out to fit the nut.
This is all I can think of, maybe others will add to this as well. Wish I'd known all of this before I started as I could have avoided some of the issues I ran into when reassembling my dash cluster. Oh well, maybe it will help you out.
Cheers!!
