Remove rear door window - New blind rivets? - 940 SW

[Metallo]

Hi,

I have a 940 SW - 1997
I removed the rear door window in order to replace the guide moulding.
In order to do so, I had to drill out the blind rivets which secure the guide channel/sliding blocks.

My question is:
Are those rivets Volvo specific? Those rivets look like olives
If yes, even ordering new ones (apparently they are supplied together with the sliding blocks), how do I fix them again to the winder mechanism?
Do Volvo dealers use a specific tool to do this job?



Thank you
