That sounds a hell of a lot like Renault. Just go to a motor factors and ask for track rod ends and your reg plate. You won't pay stupid prices, and the chances are they'll be the same part used on all the Renault range.
Renault only. Aftermarket ones are too short.
Just have a look at the steering rack, there should be a sticker with the manufacturer's name on it. Most likely to be SMI.
