Pilkington list green for 92-2000 which I believe covers the EU/UK cars....
http://infopart.org/pilkington-7915agngn-part but not sure if the JDM's are different or not..
Nippon purchased Pilkington so standards must be similar?
The only classic screen I replaced I went for a blue tint, it was only then that you could clearly see the rest of the glass was green
this was on a 93 wrx....
Can you see more colour in any of the other glass on the car? because it maybe that the screen has been replaced in the past........
PS...... Germany this year?
