hey guys, any trick to getting the rear A/c line loose from evaporator. i got the nut off but it seems stuck on there with stud. i don't want to bust it.

thanks,

On my 02, I just deleted the rear A/C, blocking it off at the front. To replace the rear heater core (which I never really used), I had to cut the rear A/C lines at the core. They wouldn't come off.
