1980 Gs450 clutch and brake parts needed

I am looking for a specific part, I do not know the name, inside the clutch cover, where the clutch cable connects to a plate. This plate in turn has a spring. The piece that "grasps" the cable broke and I can't find it locally, and before having it made , maybe someone could point me in the right direction.
The other part is the master brake cylinder, I need to replace it.

Thanks

send me a pic of what you need. BTF
