V4 sprocket carrier cannot fit V4R

Hi all, just to check if anyone has changed out the rear sprocket carrier on a V4R?

I ordered the Supersprox/AEM carrier and sprockets and carrier from Ducati Omaha. And found that the aftermarket set was thicker than the stock V4R setup by about 3mm. Both are still using 520 chains although I know the original V4 uses a 525. The left locknut wouldn't thread in all the way as a result of the 3mm difference. There is also a gap in between the spacer and carrier. Pics below attached.

I have check various parts for differences between the V4/V4R. The hub, sprocket flange, spacers are the same. Only different parts are the sprockets and the spindle is also actually different.

So in ordered to get the new sprocket carrier system to fit, should I machine down the mounting surface? Or does anyone know if there is a V4R specific sprocket carrier system?

Sorted. Turns out Ducati Omaha sent me the 1199 part instead of the V4 part. Had to send it back for an exchange.
 
V4 and V4R spindle have different part numbers. Spacers and the rest are the same. Not sure about the actual differences as I don't have the parts in hand to compare.
