Aircon - need help

I've been trying to replace the aircon rad/condensor. The rad/condensor has been changed at somepoint but the idiot who did it cross-threaded the connector on the lower right (as you look at the car) so i couldn't connect the new one. I scratched my head for a while then came up with the crazy idea of cutting off each connector and bridging the gap with a rubber pipe.

I'm not convinced this will work because of the pressure involved. The only other option i have is to replace the entire pipe that runs back to the compressor near the battery i think, but i cant see where it goes because there's pipes everywhere above. I've found the online parts manual which shows the pipe and it can be disconnected from the compressor but i need to know if its easy to get to once all the gubbins is removed from around it cause you cant see it.

If anyone had to do something simmilar or replace the compressor or got the engine out so you can see it can you tell me if its easy to get to.

If it is i need the pipe if anyones got one.

Thanks
