Roll cage install with a question

Ink,
Thanks,
I do have a CAD drawing and the measurements for the index points. No problem to reproduce. I do appreciate the NHRA rules but I have no intention of Racing the car at a track. The silver state classic has its own rule book, which I have a copy of. There are some features of the cage that are in no rule book. Ill keep posting the progress, hopefully it will help or inspire someone.
OH yeah Purple at $37 ea not a chance.
