#1 Body Mount
The mount is loose from the firewall, can wiggle back and forth
If it didn't have factory aircon, then there's a big air vent flap on the side, take that out and you can get a hand in there at the back of the mount ...easy.
If it's an aircon car the flap is not there and access is limited coming in from the base of the windshield, not much good unless your arms are long and flexible.
There is a plate exact same size as the part of the mount that's up against the fibreglass in there. Usually its rusted tightly onto the glass inside.
If it were mine I would seriously consider cutting an access hole on the side and glassing it back when I was finished. Especially if you want original type rivets put back on.
