You can get them from MC Rallying for about Â£95 but i got mine second hand (unused).
Tbh i wanted one for ages but refused to pay all that Â£Â£Â£ for it coz the quality is shocking. My painter was calling me all sorts coz he was 2 days just sanding and filling to get a good fit and finish.
Looks mint m8y, I know how your painter feels, I spent two days on mine and that was just to get it to fit and look it passable, There a b*tch to fit and thats being nice.
One thing you'll notice is the difference in the rain, you can't see sh*t out the rear window
