You'd have to replace the entire under-the-dash unit, as I recall. The automatic A/C unit has about a hundred little motors to open various flaps and diverters and such, including the recirculate air flap, whereas the manual A/C has leverfs adn cables for this stuff. There are also temperature sensors in the ductwork under the dash for the driver's/passengers control temperature in addition to the ones in the grab handles.

I'd look for a car that already has it.
