In for a horn problem, but also loose bits inside rattling around.
These are 2 coppery looking monkey metal flanges from the speaker bolt
"hank" bush/anchors into the plastic. They seem non functional, the
bolts will tighten without the remaining bush turning. 7 of the 8 bolts
would take a 1/4 turn tightening fully again. These flangey closers look
as though they are deformed in the tightening process and then burst
away at some point. Hammer and old chisel to break off the remaining six
? concerned about shearing the functional part of these monkey metal
bushes with hammering action.
