chromoly tubing, where to buy?

[NOT A TA]

Tom_a, Your car looks like it's coming out nice! Thanks for the welding link, It backs up what Chicane was getting at as well as Mikes experiences on planes. Looks like the 1 3/4 .120 DOM will be the material of choice for the main hoops. No heat treating worries, embrittlement, etc. I'll wait till I get the SCTA/BNI info to compare with the SSCC requirements before final design is determined.
