    I'm getting rid of the AC on my '83, it worked for the first 6 months I had the truck, and I figure if I haven't fixed it yet it'll never happen. What I want to know is, can the black plastic part under the hood that houses the blower motor and the AC stuff (forget what its called, but it looks kind of like a heater core) be easily swapped out for one off of a non-AC truck? I haven't made it down to the JY yet to look around.

    Was this already covered several times? If so, sorry for being a dumbass, I tried searching but didn't find anything.

    Whoops, turns out I am a dumbass, as suspected. I found the thread I assume you were referring to (11/29/01). Thanks.

    If you found dyeagers site, then thats it, also I had a bit of an idea about how to do it differently. I think I'm going to try and use a blower motor box out of a van, but I think it might be too short but they have several at the junkyard and if all else failed I could use two to make a longer one. Instead of moving the outside and inside boxes and patching the other holes in the fire wall. And remember not to disconnect your defrost vacuum line, or no defrost..

    Pete, I just went to the junk yard and found that a blazer S10 non AC might very well work with little or no fabrication, so you might want to hold off for a couple a days and I'll let you know how it went...[​IMG]

    Cool, thanks. I'm in no hurry, the trucks torn apart at the moment. I did find that working on the wiring and the motor is real easy after removing that stuff when you have no inner fenders and the tires are off. [​IMG] I really just want to get rid of some of the clutter under the hood, as well as maybe getting some more tire clearance.

    I picked up one of the S10 boxes today. Its sheet metal instead of (fiberglass?) like the stock one. I compared it to a full size AC truck at the yard, it is a few inches too short. The reason I'm thinking about trying it it that the motor turns the opposite direction of a full size one, which makes the top of the motor area higher, and allows more clearance on the bottom. The other problem I see at this point is that the coolant hoses may have to run through it. If I try it, I'll cut it in half vertically near where the air goes in the cab, and add a few inches, then weld it back up.

    If I understand what you are saying, and if it helps, the stock non AC C/K outer boxes are steel as well.

    There's no reason to get upset when the SAME questions come up over and over. Isn't that one of the reasons that CK5 is here???????????????

    I'm sure that in my first 3 months I asked some dumb questions, but people answered them, or gave me the thread to the previous discussion. Come on folks, let the newbies ask the same questions, and help them learn. I'm sure that Steve, Grim-Reaper and other "old" guys asked some dumb questions at some time.

    As for the AC removal, I tore out what came out easily, and let the rest of the crap stay along for the ride. At first I just cut the belt and left the compressor there. Then finally removed everything else that unbolted with little effort. Was actually trying to BBQ and work on the truck at the same time, and the ribs and beer won the fight.................................[​IMG]

    Sure there is. BTW, what truck can I get a 14FF out of? I have to run 16" wheels, right? [​IMG]

    The AC stuff isn't really a priority, but it may become an issue when I do the rockers on the pass side. Currently waiting on a spindle in the mail so I can turn the truck around in the garage before I start cuttin'.

    My truck has an AC cab and it is converted to non-AC with a standard full-size non-AC box. The non-AC box is smaller than the AC stuff so there is a hole left in the firewall. All it takes is a small piece of sheet metal to fill the hole and call it done. I've got pictures around here somewhere if you're interested.

    I'm assuming you had to swap out the box on the inside too?

    How about the heater core?

    I thought you were using the CUCV cab? BTW, I saw a pic of yours the other day (maybe on POR), whats the cooler in front of the radiator on the driver's side (looks OE)?

    Yes, inside, outside, heater controls, harness, and heater core came out of the CUCV cab. The CUCV cab was squashed in a role over so now it has a civi 2WD cab that originally had air.

    There are 2 coolers in front of the radiator. One is a stacked plate tranny cooler on the passenger side (not the one your talking about) and the other is the OEM oil cooler from the Sub that donated my TBI 350.

    Oh, yeah, OE oil cooler. Duh, you think I'd recognize it since we have an '89 Sub.
