The1960APE,
I am right in the middle of this. I was working out the PS hoses just today and have not solved it all yet.
I will post more info later tonight when I get on my home computer.
I have an original 6 cylinder PS Pump and bracket but the bracket you show will work too. There is a vendor who sells a reproduction of the original bracket if that interests you. I have the photos and contact info available.
You will need a double groove pulley for the water pump and harmonic balancer (crank pulley).
You will need a PS gear box from a C10 truck from 197? up through198?. CaptainFab has more details about that.
I used the CaptainFab bracket and it's a nice piece that makes the install of the Gear Box easy.
I recommend upgrading the steering shaft to a safer telescoping sleeve while you have things apart.
The back of your PS pump will have a fitting for the High Pressure hose. You will need to buy a hose to match that. The trouble I'm running into is that I can find hoses that fit the pump side but are the wrong fitting for the gear box. I'm still working it out and should have a solution before the week is done. I plan to post a full DIY on my BLOG and share the info here once I have all the info and pics completed. This is what I've done so far (shortening the steering column is totally optional of course)
