The part is built to the following specification: Fitting Position: Rear Left, Fitting Position: Rear Right, Thickness [mm]: 350 mm, Thickness [mm]: 210 mm, Weight [kg]: Zinc, 700 kg. Each dimension is checked against the OEM reference to ensure the component seats and functions correctly first time. This part supersedes original equipment references: 0293240, 0293248, 030607020260, 04.010.6000.022 and 51 more. Matching these numbers confirms a like-for-like replacement with no loss of function.
