If you get a Kombi with privacy glass sliders and want rear glass a just buy the genuine rear glass from vw in privacy too??
This also fits properly with no worries...
I believe some aftermarket glass is flat it isn’t curved and doesn’t follow the contour of the van..converters literally have to force the glass to curve ..
Completely agree with above, I bought a Kombi with the slightly tinted sliders, then bought matching VW OEM rear quarters that I fitted. I have a blank glass panel where the wardrobe is and this looks darker as obviously it is not clear.
But it does give a more uniformed and professional finish if you go down the Kombi route.
