I went to my nearest decent scrap yard today (G&R Harris' in Nutbourne, West sussex...turn at the caravans)
and found 3 K11's with useful? bits
I think they were all GX's ...so that's a silver, an apple green and a red lip spoilers
(I asked about price and the guy said they'd be £10-£20 depending on type, I'd guess the wrap around would be the £20...if he'd had any so think possibly a tenner each)
The silver one has been removed by sombody, and left and has marks where it was attacked with a screwdriver, but these are superficial.
Do you have some pic's of this
