John,
Thanks for the link for the ADs and Technical Notes.
It is a great site.

This glider has been complied with for the the 1970 Tech Note 278-2.
The C-Hook is the same one shown in this Tech Note.

I have not been able to anything that mentions using this larger
hook and bearing.

May I recommend that you make sure that you continue to comply with the
1970 Tech Note 278-2 for the Std Cirrus both for the hook and the bearing..

The elevator connection for the Std Cirrus is idiosyncratic to rig, not
difficult to mis-connect (in my hands), and requires careful checking
before flight. *Not a place for second hand or non-standard parts. *
