hi, i recently cleaned my car and moved the bonnet badge because it wasn't straight, i ended up completely taking off the badge just to have a look, n i really wanna put a new (not 2007) style fiat bade on the front, the blue one where it just says Fiat across it, is it just a case of screwing the new one on or does there need to be some modifications made to the holes on the bonnet etc. thanks very much, p.s. does anyone know the diameter of the newer fiat badges so i can make sure im buying the right one off ebay, thanks!
