comparing forks from a 2017 RC390 to a 2017 390 duke

KTM will not sell the individual fork assembly pieces you have to buy the hole fork.
Below are the parts sheets for both bikes.
They both have the same part number for the assembled forks, but the axel holder\foot\stanchion, whatever you want to call it, the black piece the screws onto the bottom of the chrome tube, those part numbers are different.

Duke: KTM.SparePartsFinderFrontend

Anyone know if the forks are interchangeable in 2017?
