Guys, i took out the glass and cleaned everything. There are 4 guide rollers that slide into the regulator. Any chance someone had taken pictures how they fit on the inside of the plate holding the glass? I forgot to take the pictures 🙂 the hardware in the picture.

Browse through the Knowledge Base area.  The articles are oddly categorised, but there's not too many.  I found one in Body and Paint, pretty sure there is at least one more.  Edit - actually, it's in the same place.  Copied link below.

Thanks all and especially @zKars this is exactly what I was looking for.

By any chance do we have any reproduction of the part 20(RH) and 21 (LH) in the picture? it is the rubber liner near the glass?

No. Reproductions.  I have some used complete windows and some of these pieces from others I’ve stripped but am away for the next 10 days.
