I'll definatey have to get my hands on some smaller rod as I always try to be as realistic as possible. While I have a lot of drag racing knowledge, I don't know a whole lot about cage rules, I have an NHRA rule book from '09 that we used for updating the chassis on my junior dragster but I can't seem to find it to look up cage specs. I want to know is something like this required? I finished the door bars and I still need to do a dash bar. I don't think I need to do a sill bar as it still has original floors so I think I'm almost done. If you guys see anything I'm missing and should add, I'd love to get some feedback on it.
