Upgrading factory A/C question
I have a factory a/c cab but thinking it might be good to upgrade to a vintage air system. Has anyone ever installed the vintage air but then hung the original evaporator box and equipment on the firewall to give it more of an original look? I don't know if this is even possible. Thanks

Re: Upgrading factory A/C question
I am afraid if it was just the "shell" it might not look right. With the top coming out to the POA valve then to he hose I am afraid if you didn't do it all it would just look fake?
No there are other options as well. Over the winter I swapped out my original evaporator to one out of a 1987 Chevy pickup (R10). This gave me the option to use the orifice and the accumulator and get rid of my dryer. I had previously upgraded my condenser so I left it in place. The weather has not gotten warm enough to do a final pressure check and know how well it is going to work. I look somewhat "stockish" on the AC and hope to have much colder air. My AC didn't work very well. I will know in a month when it does warm up. I am hoping for a great improvement. This was a pretty inexpensive option. I didn't want to spend the cash on the vintage air upgrade if I can do it with this. I know this isn't quite what you asked but it is the direction I went and hope it helps with options. Dave

Re: Upgrading factory A/C question
When I do my LS swap, I too am going to switch from POA/TXV (R12) system to a CCOT (Clutch Cycling Orifice Tube) system as found on 1987 square bodies for instance. Old Air Products (part #50-7228) will make this easy. I will convert to R134a and try the stock condenser with dual fans. If that does not work, then I will upgrade the condenser as well.

I have the Classic air group updated parts in my stock AC box. I'm running 134-A with orifice tube and it runs 36/38* on low. I had them delete the drier for the Accumulator & orifice. The AC is the same now but with the newer 6.0 LS motor installed.
The old motor 305 had the unit in it first. ![]()

I also went with the cycling system on my 69 with a 454, only I used the factory A4 compressor and had to fab my own brackets to mount the compressor

It could be done and would give the illusion of factory A/C or a more factory appearance. You won’t be fooling many people but I doubt that’s your intention. There are some vehicles that don’t look quite right when you get rid of something so characteristic so I can see why you’d want to do this. I personally don’t like recirculated air very much and will be avoiding Vintage Air in favor of updating like those who posted above.

Re: Upgrading factory A/C question
I'm not a fan of recirculated only HVAC either. It is the reason I will go with an upgraded stock system when I get my truck together. With no fresh if you ever want to drive in cooler weather you only have defrost with A/C on. No fresh and the cab fogs/frosts up almost instantly without the A/C pumping to dehumidify. That is a power and fuel sucker. There are a few months of the year here where you heat in the morning and run A/C in the afternoon. It's not a winter thing. I drive a lot of highway and no I'm not cranking the windows down at 75 MPH all the time.
