3 Point Roll Bars
When were the 3 point roll bars outlawed in NHRA competition.?? Wondering if anyone has old NHRA rulebooks that can verify the first year they were mandated & for what class/ speed/ times, etc... Also what was the last year they were legal in any NHRA sanctioned events??.
Lakewood Industries made a bolt in bar back in the 70's. It was finished in bright red paint. Any others??
