Land Rover Repair: Right rear window

Question
I have a 96 discovery. My question is what is the name of the part that secures the window to the track so it can be raised and lowered? I replaced the motor and need this part now. If you could help me that would be great . Also if you know where I can get the part as well. Thanks!!

Answer
If you go to your Land Rover dealer they have an exploded view of the door in the parts catalogue, and you can pick the window channel or track piece you want.  There are several parts that match the general description given; that is why it's best to match up with the actual parts book
