[Lanman1972]

My 1972 has dealer installed A/C with documentation. My unit is very different from factory but is not an under dash unit. Has side vents and center vent, but the dash is different and so is under the hood. The controls for the unit are on the center vent unit. Not sure if this helps. I am not sure your situation would stop me from buying if all the numbers would allow it to be plated without DMV problems.
