Only have been using drywall screws counter sunk in board. Will try to 
modify so I can use washers.

Have not used tooling holes. The comming delema is that the mylar patterns 
locating plate to bridges will be lost when bridge pins are installed and 
bridge is glued onto the board, also - after the board is glued in - the 
plate to case locaters may be unreliable. Have been taught to wait till late 
in this process to epoxy in the pin block giving some capability of fine 
adjustment if needed. Two tooling holes as you describe could easily be the 
solution.
