[Closed] Reverb rebuild seals look different

I have an A2 (I think)reverb , trying to replace the inner seal head seals but they dont look the same- I read the pinkbike article which shows the most common seals to replace and bought them.
There is supposedly a 3.5mmx9mm O ring on the inside of the inner seal head, but the rockshox videos only show a topout bumper and blue u cup seal. Is one of these to be replaced with the 3.5x9?
Also the outer seal head looks quite different, It has a female thread on both sides, whereas the pictures all have male threads
And what size is the internal circlip? This one has disappeared
