I understand the direction you were going with that cool system. My plan A hydroboost is much smaller than a vac booster and will out boost any vac booster with a nice pedal feel. Love me some hydroboost. Lol I just don't want to upgrade the OE pump or run dual pumps.

I saw a thread where a guy mounted a vac booster higher up at the main harness bulkhead passthrough grommet. He used a booster with standoff brackets to allow the harness to pass through. But he did have to enlarge the hole. But kept his crotch vent. The booster ended up about the location of modern vehicles. But that requires the pedal to go higher yet.

There is a company that makes a modern setup for the early 50's GM cars that are very similar. I send them an email asking if they ever had anyone try it in a Packard and what their pedal ratio is. It comes with a new pedal mounted on it. Also dimensions so I could see if that could be modified to fit.
