I have a 68 charger that I am in the process of restoring and currently it is a stripped bare shell. I have always been interested in adding a roll bar/cage to it.

Does anyone know of a street friendly system that will allow access to the rear seat, and still allow easy access for drivers?

I am not too interested in building a jungle gym, just a good system to strenghten the car up. Also, at what point does the NHRA mandate a roll bar/cage?

Thanks for any help you can give,

HH
