A friend has a 1975 450SL with a CD player. He needs the original model that came with his car. When that is installed, he is eligible to get collector license plates on the car. I have a 1986 Becker radio that he can have, but he wants it to be like the original. Did the SL have a Becker AM/FM/Cassette in 1975 and if so, would my 1986 model look authentic enough?

Thanks for the help!
