The Clubman F54, 2015 to 2024, is the MINI with the strangest tail: two side-hinged doors instead of a tailgate. They swing outwards like barn doors, can be power-operated, and split the rear screen in two — each half with its own wiper arrangement.
For parts that means there is no such thing as a "Clubman tailgate". There is a left door and a right door, each with its own hinge set, its own latch, its own glass and its own seals. Which side you need is the first question.
That gives the F54 six doors in total. At the front it shares its nose with the F55 and F56; from the A-pillar back everything is its own, because the Clubman is substantially longer and wider than either.
