The evaporator has been removed from its housing; the compressor is unbolted from the engine; & the condenser is loose, but still in place. The radiator has been shifted out of its cradles by removing the fan & shroud, but the coolant lines are still connected & filled. The ATF lines are also flexible enough to remain connected & filled. So if the heater hoses are routed under the liquid line (R12 only), the whole A/C system can be removed & installed without releasing ANY refrigerant, OR any other fluids. All '94-96/7 F-series/Bronco factory R134a systems have a rigid liquid line that runs against the wheelwell, requiring the heater hoses to be disconnected temporarily.

A QUICKER & usually cheaper way to do this conversion is to find a '94-96 factory R134a system still sealed on a junk truck with the same engine as yours, and lift it out as a unit, including the underhood HVAC box, and the hood latch support bracket; and swap everything without opening either refrigerant system.
