easy fix.... take off teflon washers and wrap a small piece of paper in the gap
, put washers back on , insert
trem arm...bob`s yer uncle !!
also you can steal your sis, mom , daughter , wife`s nail polish and apply multiple coats to the space for your bushes .. once dry refit bushes and off you go.. it`s a good idea to leave the arm in the socket as much as poss as constant removal/refitting wears the bushes down very quickly
hope this helps !
