My 330GT was originally delivered in Italy, thus has filled mounting holes for a Euro license plate frame. The US plate is currently held by something that resembles a bracket for a utility trailer. Definitely not correct. I thought that I had located a factory US frame to fit the car, but that did not pan out. Thus, I have no reference to drill the proper holes. I don't want to just wing it; however, I don't have any point of reference to use at this point.
Any sage advice from the forum is most welcome!
