Has anyone ever had to bend aircon lines?

Im doing turbo mods to my Patrol na I need to bend at least one aircon line to make stuff fit.

The lines are still gassed and on the car.
Basicallym If I can bend them on the car and it doesent leak, WIN. No expense required.
If I bend them and they split, or leak otherwise, well, getting a custom pipe made up was inevitable anyways so I dont really have much to lose by having a go.

Anyone have any tricks?
SUre I could just pull on the lines until they are at the right spot, but should I crack out the oxy to help a bit to avoid kinks or what ever.
