Those that have added a vacuum booster in the stock location had to modify the pedal which changes the location of the pedal pad in relation to the accelerator pedal and is very noticeable inside the car. The stock 52-55 pedal arm is on the right of the steering column so not much space to mount a booster up higher because of interference on the engine side.
The 56 pedal arm straddles the vent opening to the left of steering column and several have taken advantage of the vent opening to mount the booster. You do sacrifice the air vent but most feel it was an acceptable tradeoff. I believe all who have done this have used a different pedal with a mount location higher on the firewall. Some pedals have been from other mfgs cars and I believe one or two have used aftermarket universal hanging pedals. Those come with the takeoff point higher on the arm. Most used the pedals as shipped but one or two have modified the arms and stock pedal so as to weld on the original Packard pad setup. That way they still have a mostly stock pedal look and a location in the approximate area Packard placed them.
It might be possible but don't know if anyone has tried under the floor. Was an idea thrown around but doubt the frame depth is deep enough unless an aftermarket pedal and a booster setup can be fabricated so booster is positioned farther away and enough back so it could fit into an area under the seat. That way a piece of floor could be cut out and boxed in so booster top could be raised up slightly above the frame. Obviously a remote fill setup would be a must.
If something like an underfloor booster was tried I had toyed around with how to keep the pedal look stock. Still think it would be possible to have an aftermarket floor pedal come up using the original location the Treadlevac rod met the pedal and cover it with a longer bellows. Make some kind of roller and link arrangement to fasten the underfloor arm to the suspended pedal to allow for different or a sliding motion since the arcs would not be the same.
