Hi Jeff,
Someone may know of somewhere nearer, but Vintage Steam Products of America do it, and should be able to ship it to you:

Hi Jeff, unless you have already tried it, its always worth contacting stainless steel fabricators in your area, checking on a google search or in your area yellow pages will give details. Some but not all are very helpful with off cuts or will shear you a piece. I'm fortunate enough to have a very helpful local firm who save off cuts of all sorts in a corner for people who call in.
