Unless you've got Rover axles at both ends then the diffs won't fit. If you've got a SWB you should be O.K. If LWB then probably not. I would not recommend this conversion if you've got a standard 2 1/4 engine, and you do or intend to do off-roading/greenlaning, or very heavy towing, because you'll loose the low gearing. When off roading the low gearing is very useful for going down very steep slopes under control and esp. with a diesel the Landy will not have the power to get up some very steep slopes.
