Great responses guys, really good reading.
Basically what I am asking is if there is a way to make the 6pt NHRA legal and maximize the distance between the hoop and my head.
Door bars I can remove for street use etc, and rear seats are long gone so thats moot.
I would much sooner ditch the legal track racing than make the car full out race car.
I worry to much, drive close to 500miles a week and see some interesting stuff out there...
