Torsion bars, OEM 1971 Dodge Dart GT

Unless I am seeing it wrong, looks like one of them is an "892" bar, which would be a .87 diameter 340 bar. Where did you come up with a .81 diameter?

From the "081" stamping on the end; incorrect guess on my part?
If it is, I stand corrected, and gratefully so.
