Have any of you tried to update the cabin system to a complete new evaporator core /heater core box from VintageAir or any other manufacturer? To me, it doesn't make sense to change over to R134 with a new compressor, etc.., and leave a 48 year old heater core and evaporator core and components in place. This is especially true when the interior is already apart for a complete restoration. All opinions are appreciated.
