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.
