As you all know its awkward to get plates made for the US bezel 11 x 5.
And front numberplates, those of you that use them!...380 x 90 is quite a good size, as it fits the black part of the fascia quite nicely (thanks to Bozzy for experimenting).
They can shrink the text nicely so it fits in rear bezel without the top and bottom cut off which looks awful.
