Dear David, Take a look at Myron Toback's catalogue, p. 48. They
have a great selection of tubing and I believe if you need something
they don't stock, they will fabricate it for you. Never done that,
but could be a big time saver. Not sure how tubing is catalogued on
their website, but worth a try: www.myrontoback.com Phone:
