I have a heating and cooling control module from a 1984 Corvette and a digital control module which tells you the oil pressure, mile range, coolant temperature, and fuel range. These were in working condition when taken out of the corvette. Chervolet does not carry these parts anymore which means that they are hard to come by. They are both in good condition with a few knicks surrounding the metal frame on the digital control module which can be easily touched-up with black paint. These modules may also fit later year Corvettes. You can reach me at 248-EIGHT ZERO EIGHT-9076. Thanks for looking and have a safe and bless day.
