Few random questions

1967 C50 just FYI

Just a few random questions:

1) What all is involved in replacing the glass of a drivers door window wing. The metal is fine, but the glass is missing.

2) Anyone have info on the spare tire carrier for a C50, it sits below the frame at the rear of the truck. What's left of it is twisted to hell, and I can't visualize what it used to look like. Want to salvage what's left. Can't seem to find one single picture of one, or anything in the PDF manuals I have

3) Did these trucks come with Reversing lights from the factory?

4) What is the stock amperage on the alternators? If I'm able to get this thing running and moving, I'm interested in changing to an electric cooling fan setup mostly to save gas, but also help on power. Would like to know if my alt is up to the task of running a modern cooling fan setup that are known for pulling serious amps.

Thank you very much.
