.095 x 1.75 CM is pretty stout stuff. I haven't fooled with any but I expect it would take a decent bender to bend that. AED in Indianapolis has tubing that size. No idea what it would take to get it to you. I hope your guys know how to calibrate the sonic testers correctly. Apparently when they started using them to check bars here, they didn't. Created a lot of problems later on when they learned how to do it right. I know of more than one car that had passed a couple of times and then all of a sudden wasn't legal.
