Some weeks ago I did this retrofit to the Volkswagen Amarok of a friend of mine. It took 8 hours since we started removing bumper, till we got it back on. We had to do some trimming, because the base of where the H7 lays was to thick and we couldn't get the projector fitted in well. Projectors used are 4300k Mini H1 bulbs and Bullet Shrouds, that because of the size of the headlight, we didn't had to trim them at all. Here are the pictures, enjoy!
