Ah, but how are the hammershanks aligned to the wippens. This would not be
the first time an action got out of NY with the hammershanks all aligned
overly far to one side or the other.

If the shanks are generally aligned too far to toward the bass--check by
looking straight down and determining how they line up with the rebound
felts and the wippen flanges--you might be able to reduce the width of the
action shift stop block and re-align the hammers to the strings thereby
establishing the correct shift.

It's a long shot, but before you start carving and cutting you might check.
During the 70s and 80s I probably did this to half a dozen or so S&S grands.
Factory story? It can't happen.
