I am trying to find the dif/prop pcd or bolt centres to make up a spacer, currently don't unfortunately have my own landy to check! Would anyone know? Also centre Id and od of the locating ring. Thanks..
For a td5 90, I believe all landrover/rangerover with the ability to do body lifts have the same size flange.. could be wrong though!

 

You might want to specify what vehicle you're talking about, and then perhaps post in the forum for that model.
