Easy fix for creaking/squeaking Jazzmaster/Jaguar trees.
next time aim your camera at the work your doing. Also, just so you don't think I'm being mean, I did the same thing years ago and you figured it out all on your own. Congrats.
Where did you get the Mexican trem assembly?
Is that the GFS roller bridge? I ordered one but it doesn't fit on my JM jazzmaster
