Great DIY! I like the concept of not removing the vapor barrier completely, if you do it this way you can also buy new regulator "slider clips" and install them at the same time you do the new window "black clips", as the regulator clips do also fail. I can't see the other "regulator clip" but you may have to remove the speaker in order to get the other clip visible in order to replace the innermost one.

What are you lubing the pulleys and the tracks with? I have silicone spray and teflon spray for lubricant, and was planning on doing the black clips and regulator clips at the same time and will refer to this DIY.
