750 inner rear plastic guard

[RGP750]

The K0 is coming together well now and i have a inner rear guard but it isn't that pretty
 and the bike is looking so good i don't want to use it.
I'm looking for a new one the link here says k3 on but as far as i can see they seem to be the same after k0

anyone know if it will fit without major problems?
cheers Rich
