Before posting this question, I did my due diligence in research to avoid questions asked and answered repeatedly. I'm wanting to undertake the replacement of the 3 little round foam pads underneath the mirror on several 500 series cameras I have. The mirror is held in by little tangs protruding from the metal frame which are simply bent around the edge of the sandwich towards the lower plate. It appears there are 4 tangs, 2 at the foot, and 2 up at the hinge. Not wanting to disassemble the camera, to get to all 4, is it enough to bend just the lower 2 to allow the mirror to slip out from the front to get to these old pads? And what are the chances one or both tangs, now 40-50 years old will simply break upon bending? Thank you.
