Have you tried Car Transplants near Nantwich? 
Yeah, I'm only a couple of miles from there actually. It used to be great, until recently when they changed their policy and stopped the public from entering the yard. Now you have to order parts in advance. I find that if it's not a common part (e.g. gear knob) or expensive (e.g. gear box), they're not interested.
I much prefer the type of breaker where I can assess the condition of the part before carefully removing it myself
