JB Systems Air-conditioning paperwork request

[MD83driver]

I have recently purchased a P337H and am asking if anyone in the group has any installation drawings and part number lists on the JB Air air-conditioning STC SA32RM. Mine is not quite complete. It was installed around 1978-79. The STC is currently owned by Air Comm Corp out of Westminster, Colorado and their paper trail does not quite go back that far, only to the early 80's.

Any assistance would be greatly appreciated.
