I am starting a new project (32) and I just got some frame rails in and im going to start boxing them and so forth. I was wondering if anyone has ever ran the brake lines, fuel lines, and tranny lines inside the frame and than box it. I think i have seen a topic on this before and I tried searching for this and I couldnt find anything. I figured you would use the bulkhead fittings to go in and out of the boxed part. Anyone have any thoughts on this? I would have pressure test all these lines before I welded the boxing plate on. Any ideas appreciated! I think it would give a very clean look to the frame.
