I have a Nostalgia unit in mine but think a Vintage has got to be better. Here is a video I did about it:
Unfortunately I’m not sure anybody sells a complete ready to go kit for cucvs anymore, Nostalgic air has been out of stock for the cucv kit for a while now. The problem comes when trying to mount the compressor and keep both alternators as I don’t believe a 24v squarebody setup is made anymore.
You could convert to 12V and find stock 6.2 compressor brackets and adapt from there, or I’ve seen on here someone (I believe 79vette) fab a custom compressor bracket that mounts to the drivers side alt. Or switch to 12V serpentine belt and run 6.5 compressor brackets.
Once you get the compressor mounted the rest of the aftermarket kit should fit.

I have a vintage air kit in mine (1009, but the truck is the same where it matters from the firewall forward)
The compressor mounting was extremely annoying with the 24v system and I still have belt wear issues now years later.
Really the only good option is to go 12v and replace one of the alternators with factory compressor brackets, IMO. I really wanted to keep 24v and it was a huge amount of work for a system that still barely works/regularly breaks belts. I think it's because the belt length is so long relative to the pulley diameter and the diesel has such bad crank harmonics, but the v belt is always coming off the compressor and then it breaks. One time it even took out all the other belts due to wrapping broken pieces of the AC belt around the crank. Instant hydraulic and electrical failure on the highway wasn't fun... No power steering or brakes, all the alternator lights on...
Otherwise the kit is nice. Working under the dash is a pain but the install is not too hard.

Kinda got carried away..... M1028 rebuild
OK I am moving forward with adding AC to my P400 / 700R4 build. After researching all available options, including retrofitting a civilian setup into my M1028, I narrowed my choice down to 2 aftermarket kits - Nostalgic Air and Vintage Air. And after researching both kits, I chose Vintage Air...

If you can find the 96+ 6.5 civy trucks accessory rack it is set up for dual alternators and AC. There is one plate that will be missing. You can cut this from 1/4 inch plate and stack up some washers or buy one from these guys.

This is for the CS130 alternators which are not available in isolated ground. I drilled the mounting holes out so I could install plastic sleeves and use Garolite washers to isolate the alternator body for the passenger side alternator.
Adapter pigtails are available to plug into your original harness and maintain function of your Gen lights on the dash.

96-00 6.5L Diesel Dual Alternator Bracket
Designed for use on 96-2000 6.5 diesel serpentine accessory drive systems, this bracket sets the mounting points for a parallel CS130 alternator. This is a direct replacement/upgrade for the long discontinued GM bracket (PN10244209), with a few notable upgrades of my own design: TIG welded...

Does the engine idle up when you turn AC on if so how? Do you have any suggestions for a turbo? I need an antenna mount do you know of any close to our area? Did I tell you I seen the M1007 driving through caldwell?

I will try to answer in order asked.
No, the engine does not idle up with the compressor engaged. However, it also doesn’t slow down. The injection pump has a low and high speed governor. The low speed governor pretty much maintains the idle speed regardless of the load on it. To a point.
I actually did 4 different videos about putting turbochargers on the 6.2/6.5. Here is the first turbo one:
No, I don’t think I knew I had been spotted.
The stock fan is what Chevy used on civilian 6.2 trucks with A/C. There are supposedly different fan clutches though. I went down that rabbit hole with my 1984 6.2 powered surplus USAF suburban. I couldn’t prove there was a different part number fan clutch. But, supposedly they exist.
