The car has a/c that I am going to put back together (with R-134). I see there are a few control valves out there on Ebay, etc. Which one is correct for the '71 Satellite? Anyone have a part number for the original one? Not looking for 100% correct piece just don't want to buy something that is incorrect and will not work.

I think the 72's did as well and then 73+ got the cable operated units. If you inspect the HVAC controls themselves, this would most likely tell you what to use. If the valve is vaccum, there will be an additional vacuum line that will run back through the firewall for the valve. Otherwise, just a cable attachment to the lever and no extra vacuum line.

There are many different "configurations" on the web that say they fit the '71 Satellite. I am trying to figure out which one really will fit and operate correctly. I would love to not have to drill additional holes, etc.

It appears you should have the valve pictured above. I have holes in the inner fender like yours but not sure of the deminsions. I think the hole in the upper left is for the fuel line. You can get the whole thing (valve and brackets) from several sources, just shop around for the best price. Also, you'll need the vacuum can that sits under the battery tray. There's a small line that goes from the can and connects to the little nipple in the top of the valve in the pictured above. The other kind is spliced into the heater hose lines and is not mounted to the fender well and has a cable to it from the inside. A manual is good to have, it shows it. Hope this helps

Hope this helps The pictures, links and this description does help very much, thanks all. I assumed the vacuum line on the valve came from the heater switch to open and close it. How does the vacuum from the can under the battery tray open/close the valve? Unfortunately I only have a '69 Plymouth service manual.

The vacum control valve is available. The can looks like the air grabber type but has an extra bend in the mounting bracket. 7708363-IMG_3514_1_1.JPG (174 downloads)
