Hello,
I installed dynamo from Mercedes-Benz C200 W202, 1995 on my 164 Super T.S 144 hp engine code 64103. I only changed the clutch and directly installed it. It's only one difference - Alfa's is 80A, Benz's is 90A. Its body is the same. It's installed also on C180, C220, C220D, C250D, E200, E220D and many other models from this years.
