I put cylinders from DynoBrake on my truck and I would recommend them. Are they are a bit more expensive, but they are also overbored - takes less pedal pressure to actuate the brakes. They made sense to me because I cannot (very easily) upgrade to power brakes since I have a dual master cylinder. I liked them so much that I upgraded my drums and pads with DynoBrake parts. They claim 30% better braking over stock - believe it. Good luck with your search.

I wouldn't recommend drugs, alcohol, and violence to anyone...but they've worked well for me.
