Solving engine swap A/C problems

Nice! That's really clean!
I've wondered about this for my car (5.9 in '72) l Found a company locally that can make lines but some said O'Reilly can do that?
A lot of the auto parts stores can crimp the hoses for you, but they don't have the expertise / parts / knowledge to do custom work - adapting old to new, etc. There is a company called "Cold Hose" that has a form you can get off their web sight that you can fill out and send in with your hose / lines and they will make up a special hose / line for you. Never used them so ????. If you are looking to just purchase special fittings, they have them all at pretty good $.
