Mine has swing out rails as well. Were made a bit different than most. Fab guy had a customer leave the bar open and shut the door into it, shattering the window. Mine were made to not contact the window if that were to happen. Car is years away from being done but I can say that barring an roll over with out a belt on there will never be any contact between me and the tubes. And be honest here....if your car were ever to go upside down smashing your noggin on the cage will be the least of the problems. I do not have a back seat in my car so the cross bar is welded in. I believe Louis, the guy with the crazy *** turbo build, has a removable cross brace as well. Or at least he was talking about it. Have a ? for the op......you ever driven a high hp car on the street?? I have. Sure, keep your foot out of it and it will be a pussy cat. Whole different game when you mash the go pedal and the damn thing is trying to swap ends as it is fighting for traction. Had a 70 Duster for a brief while that had Hamburger built and tuned tunnel ram equipped 440. Ran high 9's. Car was an absolute frigging nightmare to drive on the street.
