Disc Brake Upgrade Reference Thread

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?

What is the application for that steering box? In 1980 the fitting style changed from SAE to Metric with an o-ring. If you want to use the entire '74 steering linkage, you must locate, drill holes and bolt up the '74 C20 idler arm. I do not have a template for the C20 idler arm, only the C10 idler arm. Just get ps pump with an integral reservoir. Does Davis Speed Equip not have the PS pump brackets for the early 292 like you have?

That PS pump that I pasted is for a 74 C20, with a 292.
I don’t think Davis has what I need - I just want the stock PS pump bracket. They have some strange configurations and it looks like I would have to change my water pump.

I have the front frame section that the C20 front clip came from, so I should be able to make a template for the idler arm.

I’m just trying to confirm, if I buy all the PS pump, gear and hoses for a 74 C20, it will work. Is this a pretty safe conclusion?

So, if I am correct, it seems this bracket from Davis will work. https://www.ebay.com/itm/10004-PS-PO....m46890.l49292

Saw this on eBay, seems like the best option.
