wasnt sure whether you guys on here would like it but the comment so far are really good, cheers.
Well, we had to do a bit of cutting to get the grille to fit as there are little flanges on it, then we had cut slots in it so that it would clip into the bumpers clips.
Then, obviously there was 2 large gaps either side of the grille... so we searched all over (The House, Halfords, B&Q) until we came across some old video cassette cases that had a textured black plastic look to them which was almost identical to the renault grille plastic.
We then cut this down and made up two good fitting plastic covers, these were then glued to the grille and the whole thing was attached to the bumper with the clips. Any small gaps or holes left over were then sealed with black silicone sealant.
Job done.
