GCR 9.4.C sections 2 and 3 exempt IT, SS, SM and T from the requirement of having a cage tube that extends from the forward down tube. I think STU and STL should also be included in this exemption as many of these cars cross over and without that tube, you risk running a fowl of the rules.

Thoughts?

p.s. letter already submitted, but wanted to see if I am out of line
