Does anyone know what the car requirements are to participate in Friday Grudge night racing at Maple Grove Raceway in Mohton, PA?

I've heard you need a DOT approved helmet, working seat belts and possibly an overflow bottle for you radiator? I was up on their website, but couldn't find anything. I know they do car inspections. What are they looking for?

Thanks
