Zeiss 135mm f3.5: Question aperture mechanism

[phoberus]

Hello guys

I buyed a Zeiss 135mm f3.5 with a stuck aperture and wanted to clean it. Removing the glass from one side and cleaning it with isopropanyl was not enough. I also had to clean the blades from the other side and they suddenly fell out. To make matters worse, I also broke a small screw. I took notes while taking it apart, but at this point I missed two details because I didn't know what I need to know later (did this the first time).

I would be very grateful if someone with more experience could answer me or someone who also has the lens.

1. Problem: This question is about the place where I had to replace the screw. I am not sure if I have the one lever (marked in pink) the right way or if the problem is with the new screw. I now have a better, shorter screw than in the picture. The two levers only touch very lightly and do not pass the movement on to each other.

Is the pink lever the right way?
I assume the big lever should touch the pink lever at the blue point. Is the end result regulating the aperture or is this part of the A/M-switch?
Where does the pink lever need to have a second contact point at the aperture mechanism?

2. Problem: Is the alignment of the ring correct as I hold it in the following picture? Is this called "aperture rod"?

A screw goes through each of the holes, but which hole do they have to go into underneath?
I am holding the ring as I noted in the picture, but I don't see a thread for a screw underneath.

I would be very grateful for some help. If I have put these two parts in, then I should know the next steps.

Thank you very much and have a nice evening.

Small update for those with the same lens: I have found the solution. Under the Youtube video that explained how to assemble the aperture blades, many had a similar problem as me. There I found rescue: A user wrote the correct order of the next steps in a comment. Here is the link to the video and comment: https://www.youtube.com/watch?v=U8uSwAhKp4M&lc=UgxqszKPHstrGhZpd0l4AaABAg

Afterwards, everything can be reassembled in the same order as it was taken apart. These instructions are a little easier to find. Nevertheless, here are two more helpful links:
