This may not help you since you are looking at a boosted master cylinder. But my car was modified by the previous owner to have a dual master cylinder, though mine is not power assisted.
The PO removed the TreadleVac. He located the master cylinder high on the firewall, above the steering column and beside the fresh air duct.
I'm not sure what this master came out of, but I believe it is an old Ford model. There is a proportioning valve underneath it.
For the pedal he used something massive....it looks like it came out of a van or something. The linkage is above the steering column. He had a mechanical switch, which I disconnected and went back to the original pressure switch set up.
The pedal arm is very thick and wraps over the steering column to place the pedal properly.
The pedal appears closer in this photo than it really is. It's not hard to reach , though it sticks forward a little too far.
I don't love the set up, but I don't hate it. It works and I do like having a dual master. However I don't feel like it stops as well as a factory Packard manual setup. It takes more force to do a panic stop. I have no idea what the pedal ratio is. It works well enough, which is why I haven't bothered to change it.
