Dick,
We bought our tubing from a guy who makes roll cages to NHRA spec. It's 1 5/8
OD and .134 wall seamless. I understand it to be DOM tubing. He said it was
ordered from Vincent Metals in Houston and was a little difficult to acquire.

The rule book says for 1 5/8 CAGE it should be .120
nominal thickness.
NHRA requires .134 wall now --I am shure that would
be easier to find and order-- and would pass by a ton.
Wouldn't it , list?
