[Getter-Done]

I am looking at this and thinking?

You can use an Aluminum block maybe 1.25/1.5 square and 3 or 4 inches long.

Drill a hole in (the pedal end of) this block to thread a stud to attach the clevis and incorporate the use of a jam nut for final adjustment.

Then machine a slot to accept the hydro boost rod.
Taking in account the total distance of pedal height.
Then once the location and diameter of the end of the hydro boost rod are located.
Make or purchase a bronze bushing in this location in the side of the block.

This block will be a solid push on the master cylinder.
