Start with the ITCS--10 (a)--Safety--IT cars use the GCR "Showroom Stock cage configuration" rules (not "Touring" rules).
Go to GCR Section 9.4.2. This sends you to GCR 9.4.1 F. 3 for tube dimensions :
Up to 1500 lb. car weight --1.375 x .095 DOM/ Seamless /Alloy;
1501 - 2200 lbs. --1.500 x .095 DOM / Seamless/ Alloy;
2201- 3000 lbs. --Several choices
"Alloy" includes Chrome Moly. Hence no weight break for that material

Are we limited to just Chrome Moly or there are other Alloy steels that are easy to get within a budget.
