Im not saying you'll have same experience as I did on my '50 3600 but,
Here is several options. Scroll down see if one fits your need or go to their other pages for more options. Their print catalog even has more various items.
http://www.piratejack.net/power_brake_unit.html I was told by the company it wouldn't fit my truck.
I was told by others it would require modification.
Already expecting some custom work I went ahead and bought it.
The Booster/dual cylinder fit like a charm! Just bolted right up. Didn't have any problems attaching it to the original location and brake pedal assembly.
