Mines a collection of ABused spare parts flying in generally tight formation.
For what it is worth my 1970 Std Cirrus has the smaller (14.15mm?) "C" hook, and I replaced it via the agent with no
problem last year. The reason for replacement was wear - abrasion of the hook from all the dust over 38 years.

Serial number #57 - I think they changed the size when they went to the "B" fuselage on serial number 158.

Hmmmm,
All 3 of the birds I have in the barn are 19mm, you may have a problem
in getting SH to come up with what was an early change to the design.
I'll take a look at the elevator side to see how much of a hassle it
would be to change both sides of the hook-up.

Another poster said you shouldn't consider "used parts". My response
would be; What do you think a 39 year old sailplane is, if not a
collection of used parts flying in close formation?
