Hub driver HG swap to XD driver - Surface 604 Boar Explorer

[thedeathprojects]

Hey all! I have a Surface604 Boar Explorer. I've done some major mods to it and am looking for a rear driver conversion for the Bafang motor/hub/wheel...it's a HG now and need to swap it to an XD driver....any help on this would be awesome as far as locating that part....

Thanks
