unless your going on a mega weight saving operation then dont know if its really worth it tbh, both the condensor and the evaporator are both alloy nd dont weigh much
youd need to keep the compressor which is probably the heaviest bit so belt could still run, you will need to get the system degassed(illegal to vent the gas to atmoshere)
the condensor is the radiator part, then there is the pipes and inside the car is the evaporator, would need to either block the holes where the evaporater goes into the heater box or get a non a/c heater box duct
