I'm getting ready to install the original rebuilt 230/4spd drive train back into a 1965 C10. This engine has been out of the truck for 15 years and I likely will be missing some parts. Here are a few basic questions.

Did this setup come from the factory with a fan shroud?

Does anyone have the oil and air filter numbers available?

What about spark plugs which are best for this stock setup?

What oil should I use? SAE 30?

Does anyone have part numbers for the upper and lower radiator hose or do I use flex hoses? I prefer the more original ones but it's not that important. What size hoses does the heater use?
I think that's it for now. I'm sure more questions will arise as I move forward on this project. Thanks.
