I've also asked Martyn this, so I'll ask you too Cayne: Could you ask around in your extended Polo network in the UK for one of these:
The ones with black at the bottom of the unit are Breadvan units (See Luc's picture above). Those won't fit.
Furthermore I'm looking for the unit with a
completely clear reversing light, just like in the picture.
There's also a version with a clear square reversing light surrounded by red plastic. Not looking for that.
Thanks a bunch in advance
