If worse comes to worse, having the underlevers misaligned to the key end 
lifter felt is better than misaligned hammers.

I had a late 70's M last year which hexhibited these traits. Repair involved:
Resetting the bass keyframe alignment pin.
Shimming the action over
Moving underlevers over and correcting the bends in the damper wires
Correct the shank length.

The customer was ecstatic with the results and wondered why it wasn't like 
that from the start.

I pointed out that early in the assembly process something was misaligned 
and subsequent
assembly procedures "made it work" (compounding mistakes) rather than 
sending it back
to the previous 'station' for correction.   A comedy of errors.

It just goes to show that the people in the assembly process may not have 
the overall scope
of how things_should_ work. Their job is to make_it_work.

As I've said before, it's a long way from the drawing board to the loading 
dock.
