Mats tech inspection

The big block duster that I would like to take has ten year old aftermarket belts and no inner fenders. Got the leaks, catch can, and battery hold downs covered. I'm a 55 year old beginner, the car with an experienced driver would probably run 12s or 13s but I would probably be lucky to get high 13s or in the 14 second range. Never been down a drag strip even one time. So I don't know how critical they are with tech, it seems I remember reading in the rule book that inner fenders were required
