This may not be the right forum, but I will give it a try anyways.

I think I am going to fabricate up some customization of my new Sure-Fit Vintage Air system. The basic evaporator/heater box should be useable but I want to utilize the original factory blower. This means that I could also use the factory fresh/recirculate setup. Anybody know where I can obtain the two ventilation doors and their actuators? There was one up in the cowl and another in the passenger kick panel.

With these factory pieces, I just need to fabricate some ducting from factory blower duct to Sure-Fit box and I will have fresh *or* recirculate heat and air.

Add a $20 cable operated water valve and I will have proportional heat.

Add a seperate A/C control switch and I can use plain heated defrost or dehumidified defrost, plus make the control panel function more normally.

Then I will almost have a real modern functional system. Oh, and a lot of spare parts :oops:

I know this is an old post, but did you get this done? I am very interested in your ingenuity here...

heck, you should make your own 3rd Gen system that works correctly. I would buy one, 'specially if you gave me a 50% discount for the idea!! :P

Hinshaws definitely has the cowl door (I got one last fall), and if they have it I imagine others do too. I believe that they have the kick panel door too, seems like we talked about possibly needing that one too.

No this is still just another project lined up in the queue.

The reason I was looking for this is this is how the factory A/C setup implemented recirculation. They shut off the cowl plenum intake and opened up the passenger footwell vent into the cowl plenum. Shazam blower fan intakes air from passenger footwell vent. I thought this was a pretty neat trick.

Now to figure out a way to allow the passenger vent to still work as a vent even with the factory recirculate design...

I think I have seen the cowl shutoff vent in the catalog from Chevyland locally. So one of my trips down there I will try and pick one up.

If I make something up... it will probably include enough basic tooling to make more than one. But a 50% discount??? Methinks you might be asking too much. But then I suppose that depends on what it costs me to build it since that may look like quite a discount to you. The real challenge is that in general aftermarket suppliers don't sell individual evaporator parts. They all want to sell the whole module.
