473.1.562.1A for the right side and 473.1.563.1A for the left...but even these were too wide to fit my alloy tank without interference. You have to cut about 3/16" off the outer lip as shown in the photo I attached above. If you have the wider cups that Ducati offered as the cheap warranty "fix" for and expanded tank defect you'll have to cut even more off the lip. The cups are what is causing the scratches shown in the photo of your tank. I had to file, sand, smooth, prime and paint those hacked up cups Motowheels sent me before installing them on my bike BTW.
