you will need a lefthand dashboard!
Try to get in contact with Henk ter Horst. He's my favorit for this because he has the greatest LR yard I recognized ever.
Well, Dutch people are very smart. But they speak several languages! English will be one of them. So try to get the best prize ever!
ps: forgot to mention
the conversion from right to left hand drive should be done by yourself!
