numberplates must display (ontop of reg number legalities)
* The British Standard number (currently BS AU 145d)
* The name, trademark or other means of identification of the manufacturer or component supplier (The company that made the plate)
* Name and postcode of the supplying outlet.
the problem you'll get with cropping the plate is that the BSAU number is in the bottom right hand corner of the plates. so croping the plates would take this off therefore making it illegal
