Hi I am a new member and have a question about my 70 AMX A/C. I have not owned an AMX since the late 70's and need to know how robust the evaporators are on these cars. I have the car being professionally totally rewired right now and the dash is out of the car. Hardest dash I have ever removed I might add. In any case, now would be the time to replace both the a/c evap core and the heater core. The heater core is no brainer but all of the evap core from that era I have dealt with (primarily Fords) have been virtually bullet proof. Any thoughts? Thanks much. Mike
