What all do you think is involved in doing the conversion from factory non- AC to factory AC and keeping it stock looking?
A lot. AC dash or modify non-dash, acquire AC/heater control and rebuild if necessary, acquire the duct work, acquire the blower and evaporator assemblys, acquire the BB brackets and pulleys, etc, then the condensor, compressor, hoses, valves and all the rest. And modify the firewall.
