The centre line of the bracket is 9.175±10 from Crankcase rear face (the holes are fixed horizontally by marking off from the bracket). The vertical dimension is 4.625±10 from the crankcase joint face; the holes should be drilled normal to the crankcase wall i.e. at 17°15'. This completes instructions for the above experiment.
