Hello Dominik, I have the same kit and I was wondering if you could describe a little more about the windows please. On the rear window I was thinking of cutting the glass to fit from the outside to make it fit a little more flush. Is that what you did? In order to do what I was thinking I would have to remove the two posts first and carefully remove the glass around the edges of the clear plastic until it fits then replicate the two posts removed earlier. Is that about what you did on your model? It's beautiful by the way. Thank you. Tom
