England Europe the freight would cost a fortune? There are some for sale on the UK eBay site, did not see if they were for export, there is also an alternative, put a third passenger seat in the middle with out the arm rests as the base is the same as the twin seats, in other words it's two bases welded side by side.
Other possibility is the two seater seats in the rear section, you would have to measure to see if they fit.
If you that keen I'll find them over a week or two on ebay, but do you want to pay the freight>
