States Plates will make you a set in alumin(i)um, to your design. They replicate those used in the USA. I think I'm correct in saying the front ones are legal in UK, but the rears are for 'show use' only. (My C6 passes the MOT with a US-sized effort on front, with a 'proper' UK plate on back, which I replace with the US-style item as soon as I get back from the testing station).
States Plates will colour them correctly (white front, yellow rear).
As well as the actual licence number, States Plates will incorporate other script (in smaller digits) above and below the main number
(e.g. '2007 C6'; Chevy 'Bowtie' stamp; '400/400'). That last is the HP/Torque rating for an LS2.
All easily done on the internet.
They're in France, if I recall correctly; delivery will be about 2 weeks from order.
I hope this message doesn't fall foul of 'promotional' guidelines; I write purely to onpass info. and have no connection with States Plates apart from being a customer.
