Theres nothing wrong with the rs2000 4x4 rear beam as its actually a very good set up. For simple peace of mind i would be looking elsewhere for transfer box though.

I had a good look into this a few years back and its not cheap to decently sort out the transfer box.

I gave up when i was looking at using the jaguar x type running gear as its designed to fit the ford mondeo V6 engine modified for jag, and should in theory have the right bolt pattern on the gearbox. Also should be strong enough considering its designed to take the power the top line V6 x types knock out.

The system was designed by visteon for jag.
