chromoly tubing, where to buy?

[NOT A TA]

I'm having a shop install a 10 point cage in my Firebird and dropped it off at the fab shop a couple days ago. After the shop owner talked to the sanctioning body I want to run the car in about whats required they decided on .095 1-5/8 chromoly for most of the cage.

His regular suppliers don't have tubing any in stock so he asked me to check around and see if I could locate it. Anyone have any ideas? We're in New England.
