In updating the Heat/Ac unit would you recommend to stay with the original unit or replace with something up to date such as Vintage Air or...?
Original Post
Vintage Air makes parts that have been used by Pantera owners with great success. But you need to ask yourself what you expect from your 32-yr-old supercar. the stock controls work fine except for the heater shut-off, and that is better fixed with a remote manual shut-off, which corrects the factory controls inability to shut off of hot water through the heater/AC vaporator as well as the safety aspect of rupturing one of the two short hoses under your dashboard. Adding this manual valve from a hardware store and a thorough cleaning of the 'secret' filter screen in the side leg of the expansion valve under the dash, if combined will force you out of the car with cold-ness, with a completely stock assembly. If you simply want to change the appearance of this area of your Pantera, the late wide-body cars used vacuum operated controls from the Maserati Biturbo, which have dropped invalue like a rock in a mineshaft, so such parts are cheap
