Hi everyone, I'm new here. Got a question- I just bought a 2007 CV713 and am in the process of shortening the wheelbase to put a dump box on it. I need to cut some length out of the air lines that run to the rear. They are fabric covered, steel wire/rubber lines. I'd like to find a field serviceable brass fitting. The lines all currently have female swivels. Any suggestions on where I can get these fittings and what type of lines these are? Thanks!
