yeah there are only two screws, one on the top and one on the bottom. Mine is dark blue as well and unless someone else can say otherwise I am pretty sure there was only one dark blue color VW used. As far as the 2dr/4dr being the same i would assume so but if you could send me a pic I could confirm it. If you can I will PM and address to send the picture unless you can post it here. Hopefully you have the passenger trim piece I have been looking for!
