If the a/c system is still charged DON'T break into it. Unless it's been converted ( a tag, usually on the compressor) to r -134a, you're dealing with r-12 commonly refered to as Freon. R-12 is very expensive and if the system still has some charge you don't want to loose it. Once you have the compressor loose there should be enough slack in the hoses to allow you to move it out of your way towards the passenger side of the car. Use bungy cords to keep it out of your way. That's what I did when I pulled the engine out of my Duster and you should have at least as much room as I had in your Charger.
Let us know how you make out and good luck.
