I currently have 1976 Piper Lance PA32R-300 with the incorrect King flight computer serial number. The serial # required is 065-0034-11 instead of the 065-0034-06 that is currently installed. If anyone is parting out or has a serviceable/unserviceable unit there is some interest in purchasing it. I have tried many salvage yards and avionics shops with very little luck. If anyone knows of an avionics shop that may be able to help I would love that information as well.
