Gumtree? I was looking at it also, emailed the guy to see what it was. He contacted me to say he'd have a look once back in the shop but never bothered.
Not a fan of the JDM rears, but those are a pretty good fit, you'll probably have to file out the holes a bit because they don't line up that well and the plastic screw caps won't fit back unless you glue them.
Used it, there's quite a few different ones that do slightly different things, good fun though but photoshop is king and not as hard as you might think with google there to assist you.
