HEY! Anytime you see or feel I have posted something incorrect, feel free to correct. I am not proud and learn something new everyday even on older vehicles.
I was starting to have self-doubt there.

I have to disagree with you on the system being totally unsafe. The only thing unsafe was the incorrect M/C plumbing, as I pointed out earlier. I would have also included an adjustable proportioning valve with the intent to upgrade the front drums to discs, minimizing additional plumbing changes and costs later on.
As far as the proportioning valve, turning the knob CW to fully open the valve raises the split point about 1000-1200 psi, well above the normal drum brake operating pressures-in effect bypassing any proportioning to the rear drums.
