Sedan rear bumper cover

[London Boy]

Hi there all, I need to tap your brains. I have a '05 G35x. It is time that she got a little help with her rear end. The OEM rear bumper cover is OK but just does not fit the body lines. I do admit that I have a little coupe envy and love the rear of the two door. I want to change the bumper to something that looks more in line with the body lines. 1) Have any of you put a coupe bumper cover on a sedan or 2) do you know any sites/places to get after market bumper covers.

Thanks, London Boy
