Here is a picture step by step install of my classic air upgrade kit.
Hope it helps someone.
The issues I had were:
Unisteer rack in pinion pump.
non-stock billet pulleys and AC bracket.
Non-stock water pump and housing: flow kooler and older MP aluminum housing.
Any questions feel free to ask.

(Disclaimer: This is no way saying this is the correct way to do this install. Or that I endorse any product).
