My 76 rear view mirror wobbles on the ball thing going into the back of it. I know this was discussed a few years back but I can't find the thread. It spoke of soaking the mirror so the glass would fall out, then you do something to the stud ? Anybody remember this or had to fix it. No money for replacement so I need to fix it or bubba it or something. It is so loose now it flops down when you close the door. I have tried putting glues and junk on the exposed part of the ball, but never lasts more than a week.. somehow that ball pivot thing needs to be tightened to the head. Also, can I buff that mirror housing with something to make it shine better. there are millions of very tiny pits in it and it doesn't respond to any kind of normal wax or polish. Help please.
