You could try the breakers up north the post them down to you, Ask for Barry on 00447786136752. that's the only other option then a mean dealer. He always has imprezas for breaking and the part your looking for I don't think would be taken of to many cars.
i didnt ring them didnt get a chance but because i live in tallaght i think ill check out the scrap dealers at the red cow as its only down the road ..do you know how much it was for one of them tractor???
