Adding a swingaway tongue, quick question.

I haved searched this but it doesnt seem to be that common. I need to know where I might look to find flex couplings for my brake lines. Also, any thing I should be aware of, or look out for when doing this. My check list so far:
extended wiring for lights
flexible brake lines
hinge for fold away

Brake lines from O'reilly, pep boys, auto zone, etc. The couplings are probably stainless.
