I removed the window too... it's literally a 3 second process... Just a weird angle and it's out... I used Contractors grade Hot Glue... Haven't had a problem since...
It was the very very first thing I did to my VX... as the window tab broke 2 minutes after I bought the VX... got home, got online (here) found out about the brackets... ordered them, installed them in the driver's side (haven't done passenger yet) in less than 30 minutes...
