I had a similar problem with broken jacks 20 years ago. Schaff sells replacement jacks. (Page. 123, lower left hand side). Be sure you get the right arm length.

Hi, all!  It sure was nice to see a lot of you at Grand Rapids, and to put
faces with names.  What a great resource this list is.
    That said, I went to an old Kranich and Bach grand today, that had the
board shimmed, new pinblock, new hammers with shanks and flanges.  But,
alas, not new whippens.  The old things are letting go glue joints, notably
the jack tenders.  Whoever did the job meticulously replaced all those
notorious little spring cords, but now glue joints are failing.
    Having talked about new whippens with the customer,  nothing in the
Renner kit works, or the Pianotek catalog, or the new WNG kit so graciously
given out in GR.  It seems that the K&B whip is shorter in the distance from
the flange center to the jack center.
    Anybody ever modify whips to accomplish the task?  Or what?   Besides
the obvious answer of a match and some flammable liquid!  Customer seems to
want to spend the money.
