How to switch from a DRW to a SRW in a 1981 K30 / 350 engine / 3 speed manual / 4x4

I ran my '84 without flares and just a single rear wheel. No issues. Didn't look too weird.

OP, it looks like you've got a pretty nice truck there. In all honesty, if you want a SRW truck, I'd just go buy a SRW truck. It's a ton of work to convert, it'll look goofy as hell if you simply remove a wheel. If you don't need the load capacity of a dually, either sell yours and buy a SRW or find someone to trade. You'd be much frustration ahead that way

Or pick a wide enough rear wheel and tire and go phantom dually style.

Any recommendations wheel wise ? What should i get ? Do I still get the spacers for the back wheels ?

Among other things and as you’re just doing this for looks, realize the other truck you posted has a considerably narrower flatbed, made for srw narrower track width rear wheels.
There’s not a way to make it look like that truck without a new flatbed and new front hubs, etc.
Then worry about what kind of wheels and whether you want or need spacers.

Should've seen it with busted fiberglass from one of the previous owners...

Sell the dually and buy a single rear wheel 3/4 or 1 ton. Trying to modify the dually will just ruin it and you will have a worse situation when you get done, then it wont be worth selling to get a decent truck.

While this may be a true statement wrt to the OP in particular since he has little to no understanding of what to do or even what truck he has (looks like a c&c) and likely not in the market to buy $1000s of parts and hours of labor, in general what you said has little merit IMO.
If anything converting a dually pickup, properly, to a srw would likely increase value as there is a much greater market for srw classic trucks.
Bottom line, more people will be interested in a clean srw 4x4 than a dually.
