Welcome from Texas! As others have said, rebuild your current carb. If it's original and a Quadrajet, they aren't that difficult to rebuild.
I got a kit from quadrajet power that included everything and they have videos on how to rebuild so you can follow on step by step easily.
I'm also a...
I know the tailgate panel is anodized so polishing won't work unless you remove the anodization. I used a cheap spray in oven cleaner, let it sit for a minute, then brushed it with steel wool.
I clear coated afterwards and mine is holding up fine.
No clue on removing dents. I'm not a body man...
Do the magnaflow straight through mufflers count as glasspacks? If so, I've had them on my truck for a decade and love them. The sound matches the era of these trucks so well.
It's a new switch. Is there a way to test it?
When filling it up, it does cycle until it has more freon. Then it freezes up at the expansion valve but remains cool (not remotely cold) on the drier.

Finished installing fender badges and dash badge. Officially showing GMC rep now!
Also bonus pic of engine. Still struggling with AC freon not flowing through orifice tube properly and freezing up. May just give up and take it to a shop at some point. Will be the first time this truck sees a...

I'll post a pick this afternoon of it on the truck. Got it mounted yesterday but it's in the garage so I couldn't get a good picture
What year is it exactly? '84?
I'm just curious since I've got a 76 with an 80s front clip. Figured this would hold me over until I do a front end swap in the future.
I had no clue the 77's had brown decals. 77 parts seem to always be special.
I do have a set of black oem ones I'll be selling here soon. Swapping mine to GMC as I finally got the parts to do so
