Hi Marco,

I can resend photos with the spherical washer and additional nut.

Regardless, even without those two items, the spring seems to fit in the assembly.

Hi Tyler,
there is one piece missing. After slide 4, the flange is fixed on the
spring by a conical washer, a spherical washer and then the nut.
I attached here drawings of the two washers and of the full assembly.
Let me know if you can find all the parts, we can have a bluejeans
meeting if you want.
Marco
