Cyrille,
I don't see the metal trim strip installed in your window seal. There's a slot there for that.
You definitely want to take note of how much grey goo was in your window frames. I did not, and the bottom center of my targa window is much lower than it should be as a result. You can see my process, and my results, here:

Keep up the good work, and keep those questions coming!
