I've just posted a new parts numbers page, this one showing all part numbers used on the in-cab integral air-conditioning unit '68-'72 F100/350 trucks.
Air Conditioning Unit, Factory Integral
I also started something new with this page, which is to show actual photographs of the parts listed, just for the visual aid. I don't currently have pictures for every single part, but they'll eventually be coming. I'm also planning on going back to the other part number pages already constructed, and update them in a similar manner. I'll be attempting to locate pictures of NOS pieces and using them, but occasionally I might be forced to use a shot of a 'broken-in' part until a more-suitable version can be found.
