self larnin' goin' on--narrowing rear axle

Thanks for the thoughts. I was hoping someone knew specifically what kind of tube is likely to be better. Seems to me I remember some with a name like "Shelby tubing."

last night I was googlin' around and someone had commented on another discussion that ya might look for a rod out of a defunct hydraulic cylinder. Of course one that long would be expensive, and worth overhauling, so that might be a stretch.
