A/C install-Restore

[Bullzak_83]

Hey all, I have a question, me and my son are in the process of restoring my ole 70 c10. Time to pass the keys on to my boy, the truck originally had factory A/C. Problem is all the original A/C components are gone. Through time & 30 years ago A/C stopped working had other plans and I got rid of it. I am looking at going with a vintage air system, verses going back with factory components. Vintage air around $1600.00 give or take, replacing all the original parts, around $2K, but I still have to re-plumb the vac lines inside the cab.
Does anyone have a diagram of how the original vacuum lines ran, that controlled the a/c side of the system.
And what are your thoughts on restoring verses going with a after market system.

Any feed back would be appreciated.
Thanks.
Trey

I've never restored an original A/C. I have installed 2 Vintage Air systems my self. I'm very satisfied with their product and support. It's not really difficult to install and the only special tool you may need is the hose crimping tool. Or you could just take the lines to an A/C shop. Good instructions and good phone support.

Thanks for the feedback. Thinking about it i will probably go with the vintage Air system.

Kind of in the same situation. They only draw back I have found with the Vintage Air system that uses the factory ducts is you loose the glove box. But I think that is a small trade off for what you get with the VA system.

Lux, I would like to go with Vintage but was doing a little reading and came across this on their page. Have you had any issue with parts. Also I notice that it looks like there is some kind of linkage system you tie into your old controls

Yes, the quote in red from VA makes sense to me. They don't want folks thinking they support factory A/C systems, they only support their after market ones.
As far as the controls, that's the best part. You rebuild your original controller with their digital sliders. That way it still has that old look but with new guts. It's real easy to do. And you can always get one of their controllers if you want a new look. But, not me I like that old look.

I have also installed the Vintage air system in my 72. My truck never had the A/C. They give the option for trucks that had an A/C set up or Non A/C set up. Their kits come with everything you need which I admit is rare but true. There were no vacuum lines needed for the kit.

To answer your original question, the vacuum line diagrams are in this thread. Which diagram you will use depends on how the water valve operates (closes or opens with vacuum applied) and what type of vacuum control head is in the A/C controller (2 port or 3 port).

You would only care about the vacuum stuff if you choose to get an original air setup going.

What are all the original A/C components that are are gone? The controller in the dash, all the in-dash outlets and hoses, the heater core box and lower heat outlets, the evaporator and blower housing on the passenger side firewall under the hood, all gone?

For my truck, it is important to me that I have a glove box, so I restored the in-cab A/C and heater boxes and the evaporator and blower housing. I replaced some of the in-cab components with good condition used parts by placing want-to-buy ads in the parts section here on the forum. I bought a new in-dash stock controller and ducts. And I bought an Original Air kit that includes everything under the hood except the compressor belt.
