I was thinking about installing a removable steering wheel adapter on my Pro ET 1984 Chevette. What NHRA rules would I need to follow?

Steering Wheel Scott,
NHRA Classes 7.50 and quicker in the ¼-mile require steering wheel hub to be certified as SFI 42.1. For your Pro ET car in the 2012 NHRA Rulebook on page 15, 3:3 Steering in the General Regulations section it states “Commercially available quick-disconnect steering wheels permitted (except as noted in class requirements). Adapter must be welded to shaft. All fasteners must be of a positive nature; no roll or pressed pins, no ball-lock pins, set screws, etc.”
