I had to drop my dash to work on the speedometer. When I went to reinstall it, I did not realize I had accidentally left on the ignition. I of course shorted out some things and blew the fuses controlling the radio and a second fuse that I think controlled the brake lamps (the labels on the fuse panel are worn and I cannot read the labeling on the bottom slot.) (Reading top to bottom the fuses are, INSTRUMENT, TAILLAMPS, BACKUP, HEATER, and ?) I blew the top one the INSTRUMENT and the bottom one the (?). I replaced the two blown fuses and checked all of them with a multimeter. I have front marker light and turn signals on the front and rear. But, I do not have BRAKE lights TAIL lights, and no INSTRUMENT PANEL lights. Any suggestions on where to start tracking why they are not working since I already checked the fuses?

That sucks man, I feel your pain on that one. Sorry to say that I've got no idea. I'm not aware of a fusible link that might be an issue from what you've described. If I were in your shoes I'd unfortunately be tracking power down with the multimeter point by point.

Have a look in images you may be able to figure out the unknown fuse i.d.
Did you make sure you refitted all grounds correctly when you re-installed the dash?
Brake light power comes via the switch, probably around the brake pedal area under dash, if it's like mine it'll have a spring attached, it's been a few years since I looked but I adjusted mine so the brake lights come on slightly before the brakes come on, just to give the tailgaters a bit more time.
Tail-lights power is via the light switch, you don't mention if headlights are working? On my car there's a junction block that feeds through into the trunk from behind the rear passenger seat, it connects to the rear light harness, see if you have the same, if so it's a good place to check for power to the rear while testing.

There is no doubt a gremlin in this car's wiring system. Last night after dark, I went out and checked the fuse box and the lights. I had checked the continuity of the fuses but had not checked if I had power to the fuse to begin with.
THE RESULTS: The instrument panel, has no power in, all others power in but the taillights had power in, but none out. I changed that fuse and then had tail and brake lights! I then turned the instrument brightness knob on the headlight switch and darned if they did not come on as well. I wonder if I showed no power into the fusebox because it was not coming through the headlight switch?
Now for the new wrinkle. All lights are working but when I turn on the left or right turn signal and the parking lights/headlights are on, the taillights blink on/off instead of bright/dim. This must be a grounding problem that I need to check.
My thanks to you who answered.
I'm going to leave well enough alone except to track down a probable ungrounded taillight string.
