Later Pantera's (mid '74 on ???) had a fresh air flapper door that ducted air in from the chamber below the wiper grilles to the heater/evap. unit. Earlier cars just had windows! Also, who drives their Pantera in the winter? But seriously, since properly functioning A/C removes moisture from the air, if you don't have a Pantera with the flapper door, you still have the ability to remove moisture from the air inside the cabin. I'm surprised none of the vendors have come-up with a fresh-air system for Pantera's that didn't come with one. I do recall an article in a POCA newsletter that described how to fabricate and install one. That was probably 20 years ago and the author was POCA's Master Mechanic at the time, Jack Richards. They must have given Jack DeRyke (AKA "Bosswrench") a year off !
