NEED AC HELP!
Okay guys, so I have a 78 f100 I bought right after I turned 15 and got it on the road in a few months. It's a short bed 2wd with a 302/c6 3 speed auto. It a non-air conditioning truck. Here in Florida where I'm at it's only May and it's hot!😩But I have a local junkyard called bronco dales. They have a couple dents with Ac. On that I'm looking at has all the Ac components from the factory. Do any of you have an idea on how easy it would be to swap all of that over to my truck? Please please give me some insight! Any help is much appreciated

Upper picture: Factory installed integral A/C is combined with the heater. The A/C controls are in the same panel as the heater controls.
Center picture: Deluxe dealer installed A/C is combined with the heater. The A/C switches are located in a HUGE dash bezel that sweeps across the entire right side of the dash, covering up the glove box.
A "hang-on" glove box bolts to the bottom of the dash.
Lower picture: Economy A/C is not combined with the heater. The two A/C switches are located in a panel that also contains two registers. This panel fits into the dash to the left of the glove box.

I'm pretty new to the forum. How do I do that? Or what's your email?

I'm really not in the market for something that expensive. The reason I ask is because I have all the components lined up and ready to purchase for less than cheap

Yeah, like Rich said, factory A/C can be a real pain to work on.

If you're talking about installing factory installed A/C then yeah, it can be a real pain. The problem is the firewall. On factory A/C (Ford calls it "integral A/C") the firewall is different, it has a huge hole to mount the evaporator housing. You'll either need to cut out and patch in the part of the firewall or cut out the existing firewall to match the hole for the evaporator.
The other thing with factory A/C, with that huge evaporator housing sticking in the engine compartment, it makes working on that side of the engine a bit of a pain.
If you do pull the system from another truck, two things, get one from a late '75 or later and be sure to get the two "accessory" wiring harnesses that go with it. The main wiring harness is the same for A/C and non-A/C trucks, these harnesses plug into the main harness to power and control the A/C.
Like Bill said, there are also two "Ford" dealer installed versions that are bolt on and don't require major firewall mods.
This is the hole you'll have to deal with with the integral A/C installation.

The dealer installed system is like any other aftermarket system. It fits up under the dash. These are A/C systems only and still use the factory heater.
The factory integral system replaces the heater with a "package unit" that bundles both the A/C evaporator and the heater core in the same housing.
