1972 Chrysler Imperial

I am selling this for my dad. This is what I know needs work. The shop that has been working on this car is CNC Customs in Colleyville, TX.
AC needs calibration. It has a complex system where you set the thermostat to your desired temperature and it analyzes the outside, engine, and inside and makes the necessary adjustments to make the cabin temp what you set it to.Cruise control needs repaired. The switch is broken, you can find one on Ebay.Speedometer needs to be calibrated. It shows you are driving 20 MPH faster than you really are.There is a clamp on the radiator hose that needs to be tightened. I don't have the correct socket size to make the adjustment.
