Trucktec window sliding jaw replacement - HELP
 

I bought an aftermarket sliding jaw for the Left rear of my 1994 E320. It was made by Trucktec. It doesn't look like the MBZ original, and I simply cannot figure out how to install it. Any experience out there with installing it would be greatly appreciated.

If it works, it would save anyone a great deal of money as they are available for 3-7$ at lots of outlets.

It is the exact same unit sold on FastLane as p/n W0133-1635869 for $5.69
I emailed the manufacturer in Germany and they replied: unfortunately we don't have instructions for this task.
But we tried on one sample and it fitted

Mit freundlichen Grüßen
You would think that they could at least give a hint of how to do it. e.g. does it snap in, do you have to remove many old parts, etc. Come on guys, surely someone has done it.

Maybe if you post a picture it will jog someones memory! Sorry I can't help. Hopefully someone can help you.
