Need help with the rear discharge door on a 2005 Toro 22" recycler model #20016

Hi there, first post here in this forum.

Ive been maintaining my toro mower since 2005 and this past few years its been needing new parts.
1. Both control cables.
2. Rear drag thing in the back.
3. Air filters/oil changes, blade sharpening
4. Clean and grease the pull cable components.

Now it looks like I cant limp the rear door along anymore. The thing just flops around and the pivot rod keeps coming out of the guide holes. Looks like some c-clips or something is missing. Can anyone point to links or a repair guide on this? Could not find on youtube which is how I repired the cables. Not very mechanically inclined but can do some minor stuff listed above! And I can do brakes on my vehicles!

Thanks and much appreciated!
