Obsolete Wippens

[BubaNimrod@aol.com]

Greetings, friends of the craft:

I am working on an 1894 Hallet & Davis 56" upright (scale 42B). Its wippens
have jack springs on the side opposite the jack tail, several of which are
broken. New wippens (sticker type) as is will not work, as there is a
protruding tongue at the flange end of the wippen, rendering the new wips
unlevel with the originals. Is repinning new wips with shorter jacks a
workable solution, or are there others?
Many thanks.
