Suggestion 1: Buy another (12) eye-eye forged tb's with the same thread,
swap one eye for one jaw on all (24) tb's, use (12) of the resulting e-j
tb's and hamfest the other (12).

Suggestion 2: Cut a mild steel plate that will be sandwiched between the
dual equalizer plates; it should be as thick as the sum of the two eq plate
thicknesses. Drill one edge to match the equalizer plates, and put 4 holes
in the other edge for the turnbuckles. That way, the pin of the jaw will
have to pass through only one piece of metal. Paint or hot-dip galvanize.
