This is my third thread, as I didn't want to cross the streams as per the different topics I needed help with. ALTHOUGH, if this breaks rules, I will continue in my other thread.
That being said, I am wondering if the rust present on the bridge and pickguard screws are too far gone to make this a worthwhile purchase. This Legacy is from the 90s with a 3 bolt neck (as was my question from a previous thread), however upon further inspection I noticed just how rusted some of the metal parts are on the guitar. Does this rust warrant changing the parts, or should it work fine? I ask because the trem posts themself looks rusted all the way down.
Pictures to follow. The rust is most obvious in the second photograph. Pictures 3 and 4 are just for show.
