hi... sorry but! here in oz, i can't buy the freekin' things. no one does aftermarket here. i will have to buy online from somewhere. does this otr tail tidy bolt straight on? does it replace the whole undertray like the original plastic? or do you have to cut the original somewhere to make it fit? i realise there are alot of questions. also... how much and how do i order. i'm new to this computer thing, sorry for being a pain.
