Acquired an 84 K30 parts truck

[SquareRoot]

My buddy bought this for the axles for $1500. In exchange for setting up the axles for his K5, I'm taking the bed. It's perfectly straight and rust free (S. Cali).
The bed is going on my 86 K20. My truck was t-boned long before I bought it. I have checked the frame every way possible and there isn't any damage to the frame and it appears straight. However, the body lines on the bed have never lined up with the cab. I installed new poly cab mounts but that didn't fix it. I'm convinced the metal was stretched and the bed isn't square. From underneath the truck I can see the repair ( body hammer holes and bondo) on the inside of the panel.
So, to the point. How does the bed panels attach? Are they separate pieces attached with spot welds and seam sealer?
Also, the new bed has a 3/8th hole near the front and back upper part of the wheel well. They are in line horizontally, the same height as the taillights. Are these indicative of a trim piece?
More to come...

I’ve recently completely reassembled the ‘70s bed I purchased.
The bed sides bolt on the front panel and along the wheel wells and bed floor.
There are some short welds at the bottom of the tailgate posts to the bed floor.
Those sides weigh about 80lbs each and are difficult to maneuver.

Bill, thanks for the info. Is there seal sealer or adhesive on the joints? I assume they are lap joints but my question is after removing the bolts will the pieces just come apart easily?

On second thought, I'm not sure that these holes are for trim but rather a wheel well molding. They are only present on the rear not the front fenders.

When I got my first 4x4. A 1974 gmc k10 it came with a home built 4" body lift made from 2 X 4" tubing cut into pieces and drilled holes for the bolts to go through. It was pretty floppy lol

It’s body sealer along every seam inside the bed. Mine just pulled right away, but this bed wasn’t very rusty at all, I had no stripped hardware.
The tough part for me was at the tailgate posts, the bed side is sandwiched there between the rearmost bed bottom support and the bed floor. I used a cut off wheel on the welds there but still had to use a small pry bar to get it all loose.

As far as I'm aware those holes are for the ugly door bumper trim. Those holes are too far out for wheel well trim other than the big ugly aftermarket ones, and there would be more holes for those I would imagine. My suburban has those same holes, on the rear even under the tail lights. But it does also have one on each side on the front fenders, none on the doors. Mine was also repainted at some point.
