The ceased link?

After taking apart my sons windscreen wipers and finding out that as the question before, it is not the motor that is the problem, it is infact the ceased link, we have called everywhere imaginable to try to get a replacement, everyone was happy to tell us that this part is sort after as it is a common problem with the vauxhaul corsa, however because of this nobody has them. We are in Hampshire does anybody know where you can find the full link arms unit for the wipers?
