Fitment notes

Researched from the part numbers and the donor car.

Two researchers agreed on 3 of 3 vehicles in round 2.

Sources: Fitment derived from OEM cross‑reference listings (Amazon product pages that list OEM part numbers 1644403501, 1644404601, 1644405401, 1645400101, 1645401101, 1645402201, 1645407245 and state compatibility with GL‑Class, M‑Class and R‑Class) and the Mercedes‑Benz USA parts catalog (mbparts.mbusa.com) which lists 164‑900‑48‑00 as superseding 1644403501 and covers model years 2002‑2012. / The exact number A1644403501 is explicitly listed with GL X164, ML W164, and R-Class W251 rear-SAM applications; the confirmed model-year ranges are restricted to the overlapping US-era applications, while listings that show earlier GL or ML years are treated as broader-generation or substitute-number claims rather than proof for this Revision A unit.[2][3][4][5].
