Hi there,
I have all the parts you'll need for a B7 conversion, apart from the number plate surround!
I collected the spares over most of last year, and then my wife convinced me to buy a newer car (B8 A4 Avant S-Line Quattro), so this conversion is now surplus to my needs.
Contact me for details if you're interested, I'll probably post an advert in the For Sale section if you decide to pass.
Cheers Les.
