AC Line Removal Question

[91turbogsx]

Hey guys in the middle of removing my AC components and just curious how to get this last fitting off. It appears to be crimped but I could be wrong. Just curious if anyone else has removed it? I would rather not cut it as someday down the road I might want to reinstall my AC parts.



Also curious if anyone knows if a non AC trucks heater box under the hood allows more clearance for the valve cover? If someone had a pic that'd be great.

Thanks in advance.
