Just got a 2009 xc90 from relatives in Oklahoma where a front license plate is not required. They ARE in Texas, so where does the OEM plate mount I bought attach to? I see there are four indentations on the plastic part of the grill, but don't want to just screw it into plastic. Any ideas? I heard there may be pre tapped holes in the metal behind the plastic but have not dug that deep into it yet. Figured I would ask someone else who may have had this issue first. Thanks in advance for any help... Dale
