I'm sure that can be fixed.
I'm more interested in how the back of the headlights fits. If the bolt holes align or if it is a complete hack job. Hope not...
you can see it angled up here:
that being said the fact that this is on a prefacelift S3 and you can see how it follows the line of the bumper and wing... very possibly do-able. though you would probably have to replace the ballasts with ones from the A3/S3 so that the car can talk to it properly.
DIY difficulty rating?
i think i prefer the A4 B8 conversion that someone did.
