Thanks for the advice.
I removed the complete window assembly which was pretty straightforward (see this video ) but using bike levers for tools.
Then removing the 2 screws for the central divider made it pretty easy to add the replacement glass to the removed assembly.
Finally reinstalled...
Hi,
Someone broke into my car last week by breaking the rearmost glass panel of the rear right sliding window.
I purchased the equivalent glass panel from Spector Off-Road with the understanding that I can just swap the broken glass with the new glass panel.
However I took it to get fitted...
