Re: non ac to ac
google "site:67-72chevytrucks.com ac dash conversion"
The firewall is different. It's been done, but the firewall will require metalwork. The consensus I've seen in the past is that if you want to do a stock setup, get an AC cab. Otherwise go Vintage Air or similar.

Re: non ac to ac
I did it long ago. Cut and drilled everything myself.

Re: non ac to ac
not only do you have to cut the firewall, and cut for the new vents, you also have to run vacuum lines, and find the ac parts. Then there are some vacuum valves that you will have to drill holes for. Seems like to much work for me. If i was you, i would just buy a vintage air kit, and put that in. They tend to work better, take up less room in the engine bay, and the inside of the cab. Sounds like a no brainier to me. Especially with the new R134 refrigerant that doesn't work as good with the old ac setup as the old R12 that the trucks came with originally, and you can't even get the R12 refrigerant in most places (if any at all) and is getting harder and harder to find.

Re: non ac to ac
I cut my dash and used an OLD AIR unit inside.

Re: non ac to ac
I did mine back in late 89. No kits back then like there is now for the prices they get for them I'd do it again if I found the donor truck for all the parts. Nothing to it. Having the whole AC out of another truck is what makes it work nice.
Having the donor is like having a kit + instructions on where it all goes and how.

Re: non ac to ac
I completely agree with Andy 4639. I just did my truck with original parts. Used a donor fire wall cut. I just overlaid it drilled the extra holes then used a body saw and cut both at the same time. Welded in the AC cut with no problems. Took me a day to get it done from disassembly to reassembly with new AC boxes. The interior was a breeze. Again used templates and a body saw. Done in about 30 minutes. I personally wouldn't hesitate to do it all over again. With a factory assembly manual and service manual you have everything you need to know. Vacuum lines were a breeze. I wanted an original look versus vintage air and cutting holes is a heck of a lot easier in the cab than replacing the cab or entire dash. On top of that I got every single part I needed right here and have less in it than a vintage air kit. My opinion, the sweat equity is worth it and it looks better......for what it's worth.

Re: non ac to ac
I always tell people if you have more money than time buy an aftermarket kit. If you're like me in this wonderful economy and have way more time than money I would (and did) convert using stock parts.
Check it out here: http://67-72chevytrucks.com/vboard/s...d.php?t=478564 If you scroll down to post number 8 in that link I posted a parts list. I don't know how valid it is any more but its a start.
