Picked up my first Music Man, where can I find a replacement trem for an Axis Sport?

I got it in trade. If I’m honest I really wanted to grab a Game Changer, Reflex, Vincent, Valentine, or Luthaker III signature but this was a reasonably good deal. It might be 100% my kind of guitar due to the pickups being hotter than my taste, but I can’t question the quality or ergonomics of it. It’s definitely a high-quality guitar. If I can’t trade it for something that’s more my speed, I could see myself swapping the pickups for something lower output and keeping it.

I’ve only got one question, where can I get a replacement tremolo arm?
