I imagine that the extra part on the 2 blade disc was added to professional grade victas as the standard discs are known to break apart in the middle. Unless it fouls on something I couldnt see why the 4 blade disc would not be fitted as-is with just the standard discwasher and nut (the dsc washer has the square notches in it)
