...
The equalizer doesn't do anything, and the radio doesn't sound all that good. I'll investigate that later. There's also a "performance sound" subwoofer housing in the car. The wires from it are not connected to anything.

Understand. That's just a nicely done installation. Most single DIN radios don't look as "integrated" in a 1.5 DIN hole. Obviously the EQ helps. 
OTOH, there's no telling WHAT was done behind it. :D
I'm sure you can improve on the sound.

There is an adapter to convert a single-DIN radio to a 1.5-DIN slot.  It is nice, if installed correctly.  Mine is backlit, with "Fiero" lit in red.  The adapter looks as good as the aftermarket bezels look on any other car.

That's a "HuMount". I have one on my yellow car, and ordered one for this car.

Where did you get it?  I don't recall where I got mine.

Go back to my message. I just edited it to add a link.

Was the decklid rezenforced in any way, to be sure there isn't future damage?
Not sure. The place with the cutout was filled in. But there is a crack in the brace, so I cut a piece of SMC from the deck of my parts car and glued it over the crack with Vette Panel Adhesive. And I'm careful in opening and closing it.

With the shock hinges, there should be less strain on the decklid than with stock springs.

I talked with Richard tonight and he says the subwoofer enclosure is for sale.

Found and sort-of fixed another little problem with the car. Yesterday I wanted to take a quick trip to the store, but the windshield was foggy, so I hit the wipers. Nothing. So I wiped the windshield off with a paper towel and went to the store. Today I decided to investigate the problem. I found that the wipers did work with the switch on high, but only there. A check of the wiring diagram shows that on high, 12 volts goes directly to the wiper motor, but in all other positions, it goes through the pulse board. So I took the board out of my parts car in put it in the white car. Now the wipers work on all positions, but they don't completely turn off. In "off", the wipers still wipe at long intervals, like at the slowest pulse setting. So for now, I unplugged the pulse board.

TFS sells the pulse board, or the motor with the board, but you may be able to clean the board.  Possible shorted contacts.  Or a bad switch on the wiper control.

I have 2 or 3 motors and 5 or 6 boards.  Problems with variable speeds can sometimes be in the switch in the column, especially if the car has been converted from 2-speed wipers to variable speed and the column switch wasn't swapped out.  My 86 has a similar problem.

Did the base coupes have 2-speed wipers?

The Lil Duke Coupe had 2 speed but it was a zero options car.  Variable speed were available, though. 

I found a CD4 rpo for pulse wiper system.  I haven't found a 2-speed rpo yet.

Electronically, it would be impossible for 2 speed column switch to work properly on a pulse board. The switch for the pulse board has a variable resistor in it to provide the variable voltage to the pulse board to control different pulse speeds.

Today I traded pulse boards between my yellow car and white car. Now the white car wipers work just fine. I haven't tried the  yellow car yet. I may have to get one of those pulse board rebuild kits from Rodney Dickman.
I also drained the water and Thermocure, ran water through until it came out clear, and then put in good old fashioned green antifreeze. (Have you noticed that some of these new mix-with-anything antifreezes are pee colored? Who wants to put pee in their car?) I got the air out of the system and ran it till good and warm. I haven't seen any rust in the overflow now.
