Some c#!t decided to throw a brick through my rear window to break into my car. I have gotten a spare window from the scrap yard to replace it myself but I am struggling to get the glass back onto both tracks.
I can't seem to get it onto the track on the same side as the small quarter window, I am thinking I might have to take this window out to get the main window back onto the tracks without shattering it in the process.
what do ye think? I can only find information for windscreens in the xtype , and the driver door up front is different too.

I guess nobody has ever changed one before?

I haven't changed one myself, but here is the relevant section from the work shop manual. It appears that you are correct and the small quarter window must be removed.

this is perfect thank you very much!
