SFI 25.5 Roll Cage Help

I don't have the 25.5c specs in front of me but at a minimum a rocker bar is required if the floor has been removed on any uni-body type car with a cage. I would put rocker bars on both sides of the car. The dash bar size is different depending on how your a pillar bars are bent. If the a pillar bars are broken at the dash then the dash bar is 1 1/2". I the a pillar is continuous then the dash bar can be 1 1/4". I would make the dash bar continuous across the car and attach the mid plate tubing to it.
