What is the best way to remove the AC manifold pipe

[MVK]

Hi Folks:
What is the best way to remove the AC manifold pipe that attaches to the compressor. The connection near the FI pump on the right side facing the engine looks like a trouble due to lack of space. Any special tool? Also what size nut is that?
The connection on left side below the alternator looks easy?

Any thoughts? I need to take the manifold out as its not evenly fitting the New compressor. Tried all combination of seal rings. I was thinking of getting it out and then fit it on the compressor while on the bench. Looks like the manifold face plate on the pipe might be bent a bit( I dont know how?) R3emoving will make it easy to take it to the repair shop and get it fixed on the compressor and then attach the whole assemble to the car.( MB disk tells you to do it this way anyway?)

Any thoughts. I am desperate.
Thanks
