I run a 6 point bar in my 63 Sport Fury and its legal to 10.0 since I have the stock firewall. I did not use a swingout bar as I wanted the bar to help keep the car as stiff as I could. I feel the 6 point bar stiffened the car more then the frame connectors do. I have no problem sliding over the drivers bar to get in and out of the car. Ron
