I recently took the Rear Pillars out to unblock both rear moon drain hoses and it looks like somebody before me was in there. Parts missing and the Pillars are not going back the way they are supposed to. I tried looking at REAL OEM and I could not locate these 2 Pilars and the little Torx screws in there. Does anybody know where on Real OEM these are located? Here is a picture. Both sides have the issue. If I can, I like to reassemble these with the correct parts.

Look at parts 20, 17, 18 etc.

Cheers

 

Nice. Item 15 and 20 looks like it.
