I haven't take photos when making it. It is not complicate.
The vertical trim are 20mm large chrome/PVC tape bought on ebay for 5~10€/meter, cut and fit the length of each position, glue them to the vertical part of the grill. You need to use a pre MY07 model because the vertical part of the grill are ahead of the horizon part. After MY07 is inverse.
The central of the chrome tape is covered by a black carbon strip, 3M paper used for total covering.
I pulled out the old badge with the 2 trims, cut the square badge, then glue the big round badge with the trim. put in the right position.
At final, I changed the volvo logo with a black background, ordered on a car tuning print shop.
