A handful of companies offered four-wheel-drive conversions, such as County Tractors of Knighton in Powys, Wales, UK who converted vans on behalf of Ford as a Special Vehicle Operations factory option. The first Transit County models were based on the Mk2 Transit model, both long and short wheelbase. The conversion used a Dana 44F front axle and a NP208 transfer box, both lifted from the Ford Bronco, coupled to the regular Transit engine, gearbox and rear axle using three custom propshafts. The Transit rear axle was retained, mounted to a rear subframe or 'lift cradle' to give the extra ride height. Other modifications were 16-inch wheel rims, locking front hubs, a heavy-duty steering box and 305 mm diameter front brake discs.
