If you buy a GTR bonnet, you will need to change the bonnet hinges, lock panel and lock assembly to the GTR items. This will then leave a gap where the top mole of the front bar should be.
If you then buy a r34 GTR front bar, it will fit but the edges will not align properly due to the wider fenders of the GTR unless you do some work on it.
I'm going the east bears direction and should hopefully get it within a month or so. Plastic and no mods required.
