For my Charger build, I'd like to find some .049" wall 1/2" 4130 square tubing. It's not available commercially, and I have some .065" wall on the way, but getting the right stuff would be a tremendous help. Do you have some 1/2" square tubing lying around? I need something like eleven and a half feet of it in total, but the longest section I need is 6" or shorter, so a bunch of short lengths would be as helpful as a long uncut piece. Reply here or send me a PM if you've got some you're willing to part with.
