Chris, I think they changed that part of the rule book. You can't route inside the driveline tunnel. If that includes any area between the frame rails, I've (and many others) been doing and getting away with naughty stuff for 30+ years.
The latest RB I saw said that it had to be encased in .125 pipe for 16" through the FW area.
Do Mopars actually have a flywheel when running an auto?
I had that discussion with the tech guys before, we don't.... ever see a converter on a 10.00 or slower mopar detonate? I haven't. The problem with these rules is they are too general to fit every car make design.
The cars that have aluminum line in the inner fender wells should not pass tech, you aren't suppose to have fuel lines in the tire areas. Our unibody cars are a PIA to get fuel lines run in a "legal" manner if not running steel braided line
