Unknown make, 16mm with drop links and bushes. You may wish to give it a lick of paint but it is ready to fit. What you see is what you get: £50 Collected from Herts (St Albans area) or £60 delivered.
I've managed to lose it and am still looking. Michael above has first refusal if/when I find it.
If you are interested(?), I have a Mk2 Turbo ARB on my Mk1 at the moment which is coming off soon to be replaced with a whiteline ARB.
