Technical 1940 ford

I have juice brakes from a 1940 ford I don’t like single bowl master cylinders are there any that will bolt right up to the original or will I have to replace the pedal. The one on it has 3 bolts and all the dual bowls have two bolts

 

There is / was an adapter that will allow a 1 inch Ford dual master cylinder to be bolted up.

 

Here's one. https://vintagepartsofarizona.com/pete-and-jakes-3-bolt-to-2-bolt-master-cylinder-adapter/

 

I made a similar adapter for a 40 with all stock parts except the adapter had an ange on one face of about 5 deg. to give clearance from the dual reservoir cap and the floor.

 

There is this but there may be an issue with different m/c bore sizing.
