split rims for GU Patrol

I've been trying to get some 2nd hand split rims for my Patrol and there doesn't seem to be any out there. I thought that a lot of people got rid of them to put wider wheels on and there should be heaps available. I can get them for the GQ and earlier but they have a different offset and so can't go on the same axle as the GU ones. There must be a reason, maybe everybody is going back to the split rims like Willem. Will have to keep trying.
