Meant to add for those who are adventurous enough to take on this repair, I was able to disassemble the threadlocked part of the tonearm without a strap wrench and without marking or scratching up any surface using some Robogrip pliers with rubber jaw covers. A little acetone applied for a couple days helped too.
These jaw covers seem like a very good option to use on anything decorative or crucially machined.
