Disc Brake Upgrade Reference Thread

[Asshat]

Regarding the PS gear, I was considering one from Rock Auto, like this one. It is 3 to 3-1/4 turns. Would this be ok to use? Special idler arm required? My front cross member is from a 1974 C20, so I am planning on ordering tie rods, idler arm, pitman arm and steering gear from a 1974 pickup.

Regarding the PS pump - there seems to be pumps that had a reservoir and others that did not. Can anyone elaborate on the pros/cons of both?
Also, that PS bracket for the 292 seems to have a lot of different configurations; the website from Davis Speed Equipment shows different water pump options from 75-89. Can I run a different waterpump on my 292? Is that the only advanctage/requirement, capability of runnig the PS pump?

And, do I need a PS control valve?
