Replacing the tension spring in the aperture simulator of a Nikon FG

[forest bagger]

I received an old Nikon FG for repair, and its aperture simulator was jamming and creaking.
The tension spring was rusted and broken.
I replaced it with the tension spring of an abandoned Nikon F601.

After replacing the mirror damper and thoroughly cleaning it now looks nice again.

Were the bayonet screws easy to loosen or secured with adhesive?

Easy - on the FG. Four screws.
But on the F601 - five screws - secured with blue adhesive.
