Sinze the axles seem to be pretty much the same during the 90's and early 2000's, when did Nissan change the frame? Are all coil-frames the same? I like the older patril with the sharper edges, way cheaper too, (but weak enginenes of course) but they have often rust issues. Are they als 3.5mm thick? would give the rust some material to chew on. Older Land Rover defenders often have issues with rust an the frames, but they only got 2mm thickness...
