Upgrade to power brakes didn't work

[LSUMurse]

I got a booster with everything from the rod to the pedal to the prop valve including all the brackets (it's off either a '67 or '71, I haven't gotten the info yet). I pulled my current master cylinder off the firewall (without disconnecting the lines) and installed the booster, bracket, and a vacuum line. I teed off the vacuum for the transmission (the one between the carb and distributor). Everything seems to be connected correctly.

The brakes barely work. The travel on the pedal is shorter, though it does not bottom out on the floorboard. I did the booster test (build up pressure and then turn the truck on and see if the pedal goes down further) and the pedal didn't move when I turned on the engine.

The booster came with a master cylinder of it's own (with equal sized reservoirs). Should I try using it in place of the stock one? Could it be an incorrect push rod between the booster and MC? I am using the one from the setup I bought. Should I just get a whole setup from Napa? The ones with the MC and booster connected.

Any help is appreciated.
