Your best bet if you don't wont to go to the main dealer (which i wouldn't) is to try any local 4x4 breakers to see if they have any in stock.
You could try
www.equicar.co.uk, they based in wolverhampton, but do worldwidde shipping. Last time I went down there they had a few in.
If you get stuck you could see about a bumper of a Ford Maverick as I know up an till at least 1995 these are literally the same vehicles, just with different badges.
Hope this might help
