This one passed the inspectors at Irwindale Raceway (NHRA) in SoCal. A Nomex jumpsuit with gloves, Hand Restraints or Side nets, Helmet (up to date), and 5 point seat belts. I made a wood mock-up first out of 1.5" stock. When everything fit precisely , I took it to a shop that can bend 1.750" DOM tube. He bent it and then I final fit it and welded it in place. It's removable as well..............Bruce
