1951 mercury power brakes?

Ok, fellow merc owners I am in the middle of project "Daily driver" on my 51
And am getting close. My car is on a 1968 or 9 chevelle frame with drums and I'm putting dropped spindles and discs in front.Ok now the big ? Someone started a swing pedal set up from a caddy in it and I need to get a booster and master cylinder for it and the space for the booster is really tight does anyone have this done and if so what booster/master did you use?Any help would be much appreciated.

 

If there's no room under the hood, you might consider an old timey Hydro-Vac. They were used on most medium duty trucks and I believe they are still used on many motorhomes. Mount under the floor, run the output of your existing master cylinder to the input of the remote Hydro-Vac, run a vacuum hose and VOILA! Outa sight and outa mind.

 

On my 49 Merc. (on an 80 Malibu frame) I used one from the 80 Malibu but I had plenty of room ?

 

Ended up finding a hydroboost at my freinds shop got i mounted, and i think
it is going to work great. Thanks for the help dale.
