I was planning to get a spare set of bosch injectors for my M104 3.4 amg. Most stores online states that those are the same for a very wide range of mercedes cars running cis.
But i do remember that i once tried to swap the injectors from a 420 SEL 1989 onto my 300e M103 1991 and it didnt fit. it has a different pattern on the screw side (picture attached)

anyone to confirm?
