Re the dash lights and radio, check your fuses first. They'll be on separate circuits. As I always suggest for electrical problems, get a hold of a service manual for a wiring diagram.
A common problem for dash lights is a faulty potentiometer on the light switch, turn the light switch clockwise/counterclockwise numerous times to possibly clean it. Re the radio, does it work at all when turned on? Any sound, etc.
A few of us here happen to have 66's as well. Is your's a US model, a Grand Prix? I know occasionally people call my Canadian 66 Grande Parisienne a Grand Prix. The reason I ask is because the electrical portion of the dash lights on the back of the instrument cluster is completely different between the US and Canadian model.
Also, the floor pan is not the same between a Grande Parisienne and a Grand Prix.

-fuses are all good? Do your tailights work? I am pretty sure the dash lights and tail lights use the same fuse on your car.
-test light on the fuse on each side to make sure?
If you need to work on that switch, it's a bit nasty to get at. Does the car have factory air? If so, you're almost better off to remove the dash pad from the top to be able to get at the switch.
Our sponsor at the top of the page, NOS Reproductions is an excellent place to check for floor pans. You will find them great to deal with.

Agree with Carl, my 64 Catalina was much easier to take the top off the dash then try & go up under!! Not so bad on the "back" either!!!! Might have to try Ammes in NH or EMS in Ohio for the floor pan if NOS can't help Pete

If you've never had the dash pad off of a 66 before, just know that you have to remove the cowl panel outside of the car behind the hood. Once you have it off, you will see a stud sticking through at the center of the cowl. Remove that nut before you try to pull the dash pad off inside!
Also, besides the screws going up into the dash pad from the underside of the pad, there is a horizontal stud at each end of the pad that pushes through a somewhat unique one way clip, at each end of the pad. I can post pictures for you if you like, the pad is off mine right now.

Oh, and don't get your hopes up looking for a good a/c dash pad for you car... If you find a good one, be prepared to need a wallet full of cash! They are out there, but $$$$.
