Looks like the wings are different so is the trim below the lights so they'd need changing too. = more money plus the lamps plus the wiring.
Are the swage lines between the Disco 1 and 2 the same? If not the wings wont interchange without the lines being out where the front door and wing meet.

f they're not interchangeable you could modify the 300 ones but that would need body shop skills and tools, plus paint work.
