Hello everyone,

I have a Canadian GMC 9600 with a dump box that I plan to wake up for use as a dump truck around our farm. From what I gather from the styling, I think it is a 1959 model.

The serial number on the door frame is:
Model: 9653
Serial: 99653612514D
Engine: G20626

The engine is a bit of a mystery to me. I think it may be a 261, but I cannot find a block number next to the distributor that would tell me for sure - It is painted green and the valve cover seems to match pictures of other 261s that I have looked up. It also has a Rochester B Carb that I have already cleaned up and put a carb kit into.

I have some wiring inside the cab to redo (Mice have chewed it up, and the headlights did pull enough current for the plastic connectors to melt) but I also have some other pretty big issues to deal with as well

- First off, the brake pedals goes straight to the floor, and the master cylinder looks deteriorated enough to make me doubt it will hold brake fluid in.
We do have a hydro-boost master cylinder that we pulled off of a 2009 Dodge 2500 me and my dad were thinking we could put in and delete the old vacuum boost system, but that also means we need to install a power steering pump onto the engine. Does anyone have any information on adding an extra pulley sheave onto the front of a in-line 6? There is tons of stuff for V8s, which is somewhat annoying for me.

- I think I need a water pump, but the aforenoted tons of V8 parts make me think I am not looking in the right places for parts. Where would I go for a rebuilt water pump, or at least a rebuild kit?

- The vacuum valve top cover for the two-speed axle is broken. (See image below.) What are my options for repairing this?

Thanks for any help, I'm sure I'll have a few other question as I go though.
