Does the 1994 Mercedes E320 wagon needs glue to secure the liftgate rear/back window

[dmorgan]

There are four parts, according to the diagram (see below on this post) that completed the liftgate glass kit on my 1994 Mercedes w124 E320 wagon.



On the Diagram:

1. Glass part number 124-740-01-57

2. Window Frame, part number 124-740-00-56

3. Molding - Left Mercedes-Benz (124-745-01-55-7129), Molding -Right Mercedes-Benz (124-745-02-55-7129),

4. Joint - Mercedes-Benz (124-745-00-80-7129)

My question is there anything else that needs to put in, like glue or something like that to secured glass kit on the liftgate? Or just the joint part (number 4 on the diagram) will secured the whole thing together?

Any comments, feedback/advice is greatly appreciated.
