I am having an issue, I have not started the tear down as I am trying to get the tools needed. I been told that the bottom screw (damper) screw I need a 12mm hex extended socket. I can't find one in the damn state of Ohio lol. I can't even find a 12mm hex key anywhere. I been to Harbor Freight, Menards, Lowes, Autozone, Advance Auto, Napa, Car Quest, O'Reilly's, Rural King, Sears, and Walmart lol. Before I got nuts is it really a 12mm hex for that screw? Isn't that freakishly big for damper screw?
