    It might be easier to just buy a good left control from a member here that's parting out an 850G in the classifieds.

      Hey GPZ, it just so happens that I have a left control unit on hand completely disassembled. Another member was going to take it off my hands but as it turned out, he just needed a few pics of the internals. This is from an 81 850G.



      The horn spring has a copper cup inside the plastic button. Do you still have that cup?

      Some measurements for you.

            The original one is cupped to fit into the end of the spring. It is the copper disc that actually touches the electrical contacts on the circuit board.
