Well I have two options for getting the rear window trim piece back on but the rest is coming along and almost time to get her back on the road after the long re-paint!!!!!

ALL of the gauge/instruments lamps, just the speedo/tach panel, or just the center gauge cluster? The speedo/tach cluster and the center gauge panel have different ground, so if one or the other is working, then you would be looking for a ground issue. If NEITHER panel is lighting up, then I would start with the light switch.
Did you check the fuse with a meter or light, or did you just look at it? Need to make sure there is voltage on both sides of the fuse with the light switch on. If no voltage with the switch on, then there is a problem with the switch, or it's not plugged in well.

Both the spee/tach and center cluster center panel lt by the shifter are inop. I thought I replaced the fuse but will check both sides and or put in a new fuse. I,m guessing the light switch as I had some trouble getting the light round switch back into the light fixture behind e dash. But also thought it might be a ground looking at the diagram. I know I must have shorted something when I was taking the window switches out of center panel I heard a short as I sure one of them touched something and sparked, the switches are not working. I see the large silver round breaker which I did not pull yet and have not put a meter on the wiring yet,as the windows are not in with e re-paint, I will be putting them n this fall and working on the switches then. The fuse for the dome lights and floor lights did blow but new fuse and working now. So all I see not working is the dash panel lights and center D N R light by shift. I will put a meter on and check. Thanks I will let u know why I find but am I correct it's only the 6 amp short fuse? The diagram shows another 20 fuse I believe that's labeled Tail? Thanks Mark

Wiring diagram doesn't call out specific fuses, or fuse ratings. The diagram shows only ONE fuse for the instrument lamps. 12v comes from the light switch, then thru the fuse, then out to the various instrument lamps, including the shifter light. Make sure to test the fuse with the switch ON. The fuse can be good, but if there is no power going to it, the lamps will not work, regardless. If you're going to crawl up under there, check ALL of the fuses while you're there. That way you'll know for sure which ones are good and which ones are not.

One more note.   The 20 amp feeds the parking/running lights outside the car.  Those feed the smaller fuse that powers the dash lights.  It also goes to the dash dimmer in the headlight switch.  If the exterior lights are not on, the dash lights won't light.

Parking and running and heads all working and turning knob puts on the dome and kick panel lights just no instruments lights. I will recheck all fuses and check amps as time permits. Thanks a lot . Mark

On my 1980 you can not see the instrument lights or shift lights unless it is pitch black out. The only place I could see dash lights during daytime was thru the slot on the wiper switch. Some people put in brighter bulbs but I used the 194.

First of all Thanks for all the imput I appreciate it.

I cant see my dash light only incompete darkness,fuse panel,my back is nut and bolted togeather getting to fuse box  not in this world , if you find this guy string him up with the fuse box  dwa

I got the check light working and there is light on both sides of the fuse!
