I kept the removed box just in case.
Regarding other A/C conversions:
The biggest negative is that they are using a compressor and lot more feet of hoses and they interfere with engine cooling.
Try to install a compressor on an MFI engine.
On my car the only thing you see is the original A/C vents inside the car.
Nothing in the engine compartment, nothing in front, all is hidden beneath the carpet.
