What year is your GTI? The side GTI badges are for the '90 spec inwards trim. There is a space (recessed not-textured oblong shape at the end of them at the front edge on the doors. The GL models had the same trim, but instead of the GTI badge, they had a tetured plain badge with tiny squares. If you look at the car thread in the mk.2 Golf section, there will be some pics of the new 16V badges that I put on and you can see where they go from other pics of the car.
