AC Parts

So I have removed the underhood AC components from my D100, I’m planning on sticking them in a box on the shelf unless someone has a use for them.

Is there much if any value in original AC components and brackets?
The crankshaft pulley is the hardest part of the under hood parts to find, next are the hoses. I don't understand why people want to remove their ac system to begin with unless it's for competition reasons. Vehicle's get better mileage using the ac rather than rolling down the windows and yes this is coming from direct personal experience.
