I was at the junkyard the other day and could not find a heater/AC control panel. What I did find is a ton of different Adam panels that look like they may work. So many 6 vacuum ports in the back for controls and a couple more ports off the temp area. Has anyone ever tried to fit the newer 80's control panel into out coaches? They are plentiful and cheap, figured I would ask before my attempt.
Here is an example of what the assorted vacuum ports do at the various settings for the second generation A/C configuration: http://www.gmcmhphotos.com/photos/color-hvac-troubleshooting-charts/p22988-hvac-connection-charts-color-comp.html
