I was looking through my old photos and came across these pictures from a car that had AC installed at the dealership. Putting them on here seemed like a smart thing to do.

912E AC Install Pictures. I believe these are factory A/C setups.

ALL A/C was dealer installed.

Including 912E?

Here is mine. '73 1.7L (it's FOR SALE btw )

I have one of those (the first set of pics), would it be worth rebuilding? If it does get working would its use drop me to the same gas mileage as my avalanche? Is there supposed to be a special switch for it on the dash somewhere? Sorry for all the questions, I was just wondering about that thing for awhile.
