Picking up an old Bracket car. Have some questions

As mentioned check everything over. The roll bar may or may not be a problem, true it's not required until 11.49. If it's mild steel it must be at minimum .118" thickness and 1 3/4" diameter. It could depend on the guy who techs the car, if a roll bar is there it has to be 1 3/4", if yours is not he may not let you run.
