A/C Fresh Air Door Brackets - The 1947 - Present Chevrolet & GMC Truck Message Board Network

**Sheepdip** · 10-02-2019, 11:27 PM

I'm trying to get my A/C up to snuff (now that summers over) and ready for next summer but I can't seem to find these 3 brackets for the A/C fresh air duct. Seems LMC has everything but those 3 pcs, I've tried other suppliers catalogs with no success. Maybe make some phone calls tomorrow unless someone here can send me in the right direction. I found this photo on an older posting.

I guess if need be I could reproduce them myself but I'd much rather purchase them.

Something you may want to consider, is just eliminating the vacuum pot and hardware all together. I know some on the board have sealed the door closed with no ill effects. I have mine working, but really never set it to outside air.

If you block it off completely you'll never get fresh outside air in the cab, which isnt a problem when using the A/C, but will fog the windows up when using the heater/defroster. It's really annoying.....

Well from my research since last night it appears these parts are not reproduced, so I'll keep my eye out for someone parting a truck on Craigslist, maybe I'll get lucky.

I do have a buddy who has a Factory A/C Blazer I can put an eye and tape measure on them. They appear to be a simple fab job but having correct dimensions to start with helps.
Good thing is I don't need them like yesterday.

Also keep an eye on the parts board here, you don't need to be a subscribing member. http://67-72chevytrucks.com/vboard/forumdisplay.php?f=8

However, subscribers can place a WTB post (among other benefits) which might help you find stuff you need. It's money well spent IMO.

You can't buy these pieces aftermarket. Trust me - they are rarer than hens teeth.
A WTB post is how I finally found them for my truck.
Good luck!
Also, there is another piece that supports the flapper under the cowl vent that goes into the firewall.

I did away with mine several years ago. My truck isn't a 100% truck so no problem with shaving it. My AC runs at 38* all day long no matter what the air temp is and if you need a little outside air you open the drivers side foot vent are open the vent window.
Closing off this keeps engine heat out of the cab for the most part since it's vacuum operated it has to be working perfect are you will have heat sucking in. Plus hot outside air all the time.
With it closed off you get the same effect as in a late model vehicle set on recirculate are max air. You leave the floor vent on the passenger side open all the time and the AC keeps cooling down the air in the cab. I took the vacuum off the passenger floor vent also and put the manual pull handle back on it just in case I do need it closed.
Sorry the parts are long gone.
