power brake booster, will it work?

[ktgooch]

saw this on ebay and wondered if it would work "1955 to 59 Chevy Truck Power Brake Booster Frame Mount Pedal Assembly
Chevy Truck Pedal Assembly
This pedal assembly is designed for 1955 to 1959 Chevy Trucks. It bolts to the original spot on the frame. Comes with a 7" dual booster and master cylinder combo (for disc/disc or disc/drum apps.). This will work great and you can buy it for a fraction of the price of other suppliers" im just wondering has anyone tried it? i was planning on keeping my same drum brakes and all. i just dont wany to drop $200 with out some improvement. thanks
