My german is not as good as my english but here we go:
Shifting side
First sketch:
Threaded rod with 6 mm thread LH and RH thread.With locknuts ( contermutter) Lenght of the rod to suit.
2nd sketch:
When you have access to a lath:
Original shiftlever.
To be turned outof a large bolt so that shiftlever can be mounted with little play.
What he means with VA bolt I do not know, probably the material.
Grundplatte = Baseplate ( I presume you have the drawings for them)
Sidestand mounted with a "U" profile. Use the original sidestand. fix with bolts and capnuts.
Sketch with "1": Piece of steel to limit the travel of the sidestand.
Sketch with "2" Manufacture a similer bolt as for the gear lever.
This concludes part one of the translatoin. I have to study the layout of the "bremsseite"= brake side and try to understand how he did this.
Till tomorrow
