Many (many!) years ago, Tormach noted that their TTS collet was just a standard R8, ground flat on the face. If the LMS & Tormach collets are out of spec -and the numbers you post are definitely out- just grab a good one and grind it flat (and square, of course). I do understand that not every shop has a surface grinder, but you should be able to find someone. Probably get a batch price for several that would make it reasonably cost effective.

IReminder: the TTS collet is intended to retract slightly below the surface of the spindle to index the TTS ring against the spindle, not the collet. Absolute length of the collet is not as important as long as the ring indexes to the spindle nose. A flat face square with the axis is the "right" way to do it, but squareness of the collet face doesn't determine indexing unless it prevents seating against the spindle. One could probably flatten the collet on the side of a bench grinder wheel and get a workable, if ugly, result.

If I got collets with that kind of runout, I'd send 'em back.
