The fuel/oil/temp pod is interchangeable between all sedans (except 036, which is calibrated differently due to the 90L tank with shorter fuel sending unit). The speedometer is interchangeable, if you plan to use your existing 400E speedo, that's fine. The tach is specific to the M119 engine. The warning light indicator strips are replaceable, if you buy a cluster with different indicators, you can swap out your existing one.
