Urgent Part Required for DESC210

[Devils_Penguin]

Hi Guys,

Im hoping you can help me. I am desperately looking for a part for my Team Durango DESC210. I am looking for a rear suspension arm (Part number TD330381) but I cannot find one anywhere.
I realise that they have gone out of business, but I am hopeing that someone somewhere has a spare hanging around.
I am based down in Dorset, UK, and would appreciate any help I can get.

I have added a picture of the part the broke.

P.S The other picture is here to help you take pity on my poor little lady and her broken leg

Thank you in advance.
