Front bumper/rear lights

[Super Ace-K]

Been looking on club s12 and seen that alot of the s12's have a different style of front that doesn't have the rectangle mould on the front like UK ones have for the reg plate. Was wondering what way it could be changed to fit square import style plates? Also the rear middle section, seen ones with a square middle instead and also square rear lights with reverse lights in the bumper below. Are these an easy change or fairly easy to source even?

Cheers
