Thanks, had a look, but with shipping, duty and VAT is still quite pricey.
Emailed them to ask how much they would cost, although not sure in what condition they would be given the state of the car!
The other option I am toying with is ordering from Amazon Japan. The part itself is only £125, a parcel forwarder would charge £40 to send it to the UK, and roughly another £30 on fees.
