Speak to your Schempp-Hirth agent of Schempp-Hirth themselves.
Schempp-Hirth were extremely accomodating with the tailplane bush
replacement kit for my Std Cirrus (and later winglets). Almost all of
their staff speak English

Also see the Std Cirrus website and its Forum - over 330 owners there.

For the tailplane diagrams from the home page select
'issues' from the radio buttons just under the web page title
then select
'elevator'

Bottom line - fit the right part and ensure that it is fitted/adjusted
correctly - control surface movement/measurements iaw the flight manual.

Good luck.
