My tube swap worked out. In all honesty it wasn't that tough after all. It was actually tougher to find the tube than the board. This one came out of a Phillips tv. A little work and all should be well. Here's what I got.

Here's the original, also a Phillips tube. Unit had so much burn in that you could read it across the room.

The connectors weren't the same. Good thing I had wire cutters

This is the back of the tube and chassis after I spliced in the connectors.

Here's the tube with the old chassis. They don't fit. Going to have to make a new holder.

That's where this all comes in. Jigsaw here I come.

Here's the new, swapped tube looking good.
Lessons learned:
You can swap a 20 inch tube to a 19 inch chassis. However, I've never tried this with a different mfg'r. I figure it's probably safe if you use the same make but I wouldn't chance it.
Connectors need to be swapped. I used crimps. I'm sure solder will wok as good if not better. The problem is that one monitor had stranded wire and the other had single wires. I didn't want to desolder it because it was a serious mess.
Unlike what has been said in other places, I was able to keep the original yoke. You'll see that the pics show the convergence is alright. I mainly kept the yoke becuse the neck of the tube was a different diameter.
That said, it worked and I'm satisfied. I just need to cut myself a new mount out of particle board and I'll be happy. Will post pics of the DD restore later.
