mazmonza, when I was doing the glass replacement after mine broke, I went to the drawings of doors at MB EPC and on SLS and I bought all the plastic and rubber parts that are there and replaced them for new ones. Quite a lot of them there.
Also the clips rubber bumpers holding rods for locks.
There are rubber or fabric stripes between the glass and a rail holding it from the bottom. There are also 4 bushings going through the orifices in the glass for screws.
The jaws replacement process is very well described in the Tech Manual.
