Hey I saw your posts on R2 B2L's post. I do really like the fitment of the new front end, the body shop did a lot of prep to it as i think they would for any aftermarket piece.
I did have the body shop mold the signal lights in. They made up some steel brackets and fibre-glassed them in behind where the lights would go. They they placed the lights and fibre-glassed around them to make it look as if they were made for it.
Only thing that is hard to get used to is that I went from a twin element bulb to a single, so now the flasher blinks faster. not a big deal but the ticking can get annoying quicker.
One issue I've had with mine is keeping the mesh in place, the body shop fibre-glassed in some wires to wrap around it but they break off and bend away very easily causing a lot of frustration when washing the car.
