Having a very hard time finding a working an HVAC panel for a pre 82 car with A/C to finish the mechanical end of my restoration. The A/c is not a must have but would be great if available.I have gone through 5 panels and can't find a one with the rotary switches in complete working order which is all I am concerned with.Any help will be appreciated. You can email me direct at bnpoliakoff@yahoo.com if you can help me
