In the article relative to that '51 Chevy, there was a picture of the engine and along side was this rather small looking brake booster.(pg 212)
I have a Streetbeasts Vicky with floor mounted pedals(brake and clutch) and would like to add the luxury of power brakes. Would it be possible to find out the actual make, model, part number of that brake booster?  

I believe it's a stainless steel brake Corp. model check around here www.ssbrakes.com
