If I'm reading the NHRA rule book correctly, there is a discrepancy on pg. #76, 4:10 Roll Bar.

In diagram, 4:10, it states, "All materials must be 1 3/4" O .D. mild steel ................except A, (rear braces that go into the trunk) which is 1 1/4" O.D.

In the paragraph just above the diagram, it states: "Rear braces must be of the same diameter ,,,,,,,,,
as the roll bar.

Which is it? Can I use 1 1/4" for the rear braces or do I have to use 1 3/4"?
