    NHRA Chromoly roll bar specs are 1 3/4 × .083. General regulations section 21 page 21

    SCCA roll bar specs 2700lbs and up are 1 3/4 × .095 Page GCR-91

    My question is, to build a roll bar compliant with both rules, will SCCA allow the 1 3/ 4× .083 for Chromoly? The rulebook did not specify different thicknesses for DOM vs Chromoly.
