need advice on undertray

i have ordered an undertray for my sv650s k3 model from this site:

i only ordered it yesterday and waiting for it to turn some time in a week or two, i am looking at fixing some form of tail tidy to fix up the rear end look of the bike. does anyone know if the pyramid plastic undertray comes with fitting to fix your number plate and indicators to it.

also i have heard you need to saw off parts of the orginal to fix the undertray on?

if anyone has any pictures of showing how to fix it on and any parts i need to get the neat sports look i am after would be much appreciated, as i am ordering parts for bike not knowing if i need any other parts or fitting. to still keep the bike road legal
