Someone suggested we post GMC trivia...
if the 23 and 26 ft coaches all came down the same assembly line how did they coordinate getting the right length body on the correct length frame when completing the "body drop"?

I don't know but the mfr's appear to know how. At one time AMC made ALL models, Ambassador's, gremlin's, rebel's, etc, intermixed on one final assembly line. Quite the sight to see. Ya wanted to just stand there and watch to see what would happen if they got it wrong.

I've walked through assembly plants for a few decades, but not worked in one for more than short periods at a time. Someone who spent some time in manufacturing engineering could explain it better, and GMC's are a little different than a mainstream car or light truck assembly processes. And, there is a lot more computer automation in a plant nowadays, but even in the 70's a fair amount of sequencing was done by computer. It sort of works like this. Both the body and the chassis start out as somewhat "generic" although there may be a few variations of each even in the early stages. In the case of GMC's 23 & 26' are obvious distinctions. In the 1977 Chevy Impala plant I spent a summer assignment in, there were 2 doors, 4 doors, and convertibles, which are similar distinctions. On the chassis side, disc or drum brakes, manual or auto trans, and engine size, as well as chassis length were discriminators. As more assembly is complete, (in the old days for car plants, often after paint for bodies, and after the powertrain is put in for chassis) the body and the chassis are "sequenced" to each other, arranged on a moving line (still separate for the body and chassis) where the bodies and the chassis are hung in the same order, which is then associated to each other even though they may literally be a mile or so apart. That point is still pretty early in the process, as if you think about options, things like cruise control require some parts mounted to the engine (which is part of the chassis) and some mounted to the body, such as brake pedal switches and wiring harnesses. So, to make a long story short, there is a lot more than just chassis length to keep together. People can and have spent entire lifetimes devoted to efficient sequencing strategies for assembly plants as you trade off things like trying to keep the same colors together, (less purging of paint booth lines) while not violating time restrictions, that maybe no more than 3 units in a row can have air conditioning, or whatever.

The Ford Assembly plant in South Chicago was my client in the early 1970's. It was interesting watching them put cars together. The interesting part was the body went on in pieces. They always managed to get the same color bodies to matched the correct fenders and hoods even though they came to the line by different routes and were painted at different times.
On rare occasion when there was a mistake, they just went ahead with the assembly and pushed the car off to the side with the ones that would not start. The assembled cars did not stay at the plant. There was a crew of men that got in the cars at the end of the line and drove them about 4 blocks down the street to the rail head and truck loading facility.

Talking about mismatch:
I got Grace a 2014 Buick Enclave, we had selected the car, but today they told us that they found a dent in the rear, so they offered 2 choices. You guessed it, they were more fancy than the ones we selected.
What does a slant eyed Ornamental to do with DUEL MOON ROOFS ?
Just have to use tooth floss as sun shades when I get in.
Grace will need to do the same.
Oh, I will take the tooth floss with us when we pick up the car and have fun there.

Matt,
Thanks for the input.
My last question really was more rhetorical/humor -- but it is a 23 and and early body.
I was more focused on the "trivia" of why my frame was marked 23 on the front and adjacent sides -- I suspect somewhere in the assembly process it was difficult to tell the 23 versus 26 and it was easier to add the marks.

Dennis,
I doubt it very much. The picture is undoubtedly a test assembly. Yes, it is a '73 23' (see the windows), but there are some problems. If you notice, it has Toro wheels - Not GMC. There are no wheel well liners in then front. If it was finally assemble, I would expect there to be a collection of things that require connection hanging from the body. This does not mean that you did not end up with this body or chassis, but probably not this assembly.

Matt,
I agree if you look carefully it appears that the building is empty there is nothing around the GMC at all.
