Turns out my 67 Frankenstang is only about 25% 1967 and 75% "other", including the brake system :(
It came with a non-power single-piston front disk setup, which I now know to be 68-style. It also had a brake warning light distribution switch. I subsequently added a Midland booster.
It's currently all apart and after several attempts to order the right replacement brake lines, I've come up still not getting what I need.
Does anybody have the proper diagram that shows what the proper makeup is of this system? That is, what lines are required? Is a proportioning valve part of the original system? Is the brake warning light a separate piece originally or a part of the proportioning valve?
I'm looking for a diagram like the one in my (unforturnately not-applicable) 67 Ford Shop Manual, figure 21.
TIA,
Joe
 
OK, got this diagram from Mike in San Antonio.
I have only the basic distribution block, shown in the photo below.
Thanks for the help!

I confirmed on the schematic for the 67 that they installed a prop valve at the back axle on disk cars in that year only.
Just crawled out from under the Frankenstang and I have no such prop valve at the rear axle. I suppose I can conclude from all this that my car was originally an all-drum brake car that a previous owner had installed 68 front disks on, without the addition of a prop valve.
I'll either have to come up with an original prop valve, or plumb in an aftermarket one.

You would have had the distribution block with brake switch regardless of disk or all drum brakes. My 68 is factory all drum manual brakes (soon to be upgraded) and I have this setup. As for a proportioning valve, yes you should be running one with front disk setup. You do not need to plumb it in the rear, you can plumb it up front if it's easier for you.

I think I'll get an aftermarket adjustable one and do like you said....plumb it up front where I can fiddle with it.
Hopefully there will be rear disks at some point down the line, so I'm sure that will call for some tweaking of the knob.
Thanks!
