Does anyone have any spare original black plastic coloured side and rear sills, like the ones show in this thread

The doughnut previous owner decided to spray them silver (badly) then decided to spray them black again to cover up the mess
Now the black and silver paint is flaking off leaving them in a mess.

I'm hoping that someone might have them spare in their garage or maybe braking a signum, i'll pay good money for them.
I live in Brighton at weeknds and Wales during the week so can collect if your near.
