73 Grande will be used to build 73 Vert.
I would like to remove the power brake unit from my 73 Coupe (so I can put it on my 73 Vert), and was hoping to make a non power brake setup work (since it will be a roller at some point). Here is what the firewall looks like:

Those 4 studs; is there a bracket that mounts to it to allow a traditional master cylinder to mount there? Or does the four studs mean that you have to have a power booster installed? As usual, thanks for the help and education.

I don't personally know, but is your vert a factory manual brakes car? If so you could compare what you firewall looks like in that car. My car was a factory power brakes car, and it had the plate with four studs on it to mount the booster like your pics. I would assume there is a plate for manual brakes cars to mount the master cylinder directly to?

The manual brake master mounted to the upper two holes in pedal support bracket. The manual brackets had a threaded insert, so you'll have to nut & bolt the master. You'll also have to add a pin for the master pushrod, as the power pedal's pin is lower on the pedal.
 
The pedal will need a pin added (unless you can use one from a non power brake car) The pin will need to be 2" higher than the power brake pin.
Here's a pic of my pedal arm, but I was going from non power to power.
