the armrest design changed slightly in 03, you can definitely swap it, same screw placements and everything
armrest assembly can be removed via bolt that goes in from the driver side of the armrest hinge, located after plastic cover is off, easily removable by just pulling on it, THAT EASY!
however, if this is removed you have this gaudy aluminum bracket waving at you and it's an eye soar, VW offers a cover for this
center console is easy to remove, it literally snaps off, or philips head screws after removing top plate
for automatics you need to remove shift handle SOMETIMES
anywho, i hope i helped and feel free to email me
thanks
