Has anyone done that?  Thinking of doing that and would like to call on anyone who has and what problems I could encounter.

I agree, pedal ratio makes a big difference. 6 to 1 and a MC of 7/8” or smaller normally do not need a booster. I remember my dads new 55 sunliner he had the dealer add a Bendix booster. It was a lot more sensitive than the 56 Victoria which he didn’t add one.
When I changed rear ends in my 56 the brakes came off a vehicle with power brakes and I changed the wheel cylinders to a smaller size. Also 4 piston or 6 piston calipers seem to work fine without one. There are a lot of options and opinions.
