Hi Tony

From my understanding the wavy washers are there to alter the forward & aft position of the rotor to take up machining tolerances and I doubt there is a position for these washers which is the same for all P70 engines. Personally I would clean off any rub on the intake and put little strips of insulation tape in the compressor blades and place the inlet back on tight, If it tape makes the rotor tight to turn then I would take one of the three washers from the front and put on the rear.
