Can this be done and what does it entail? I have read the guides on converting form double to single grill and from Single to S-Line But can an 8P1 be converted directly to a 2009 S line front? I'm guessing it needs, Bumper and Bonnet, but will it need lights and wings too? What exactly will i have to cut back on the crash bar? So on a pre 2005 A3, what else will be needed to fit this bumper other than the bonnet? Thanks in advance for the help guys!
