Roll Cages: Chromoly VS. Mild Steel

Google AED metal they sell mild steel and chromemoly and have a weight per foot chart and you can ordrer additional chromemloy tubing alot cheaper from them, i installed a c/m 14pnt cage in mine and yes i migd it it can be done and its a street car only so i dnt wana hear nhra says this and that about mig welding c/m. i called professional circle trak chassi shops who build c/m chassis and they mig as well and they take alot more abuse than a drag or street car will ever see
