Another project slated for my 1960 LeSabre Flat top is the sound system. I spoke with a fellow from a local antique radio club. He states he can take my original radio and add a 'new board' to it along with an auxiliary port and I will have the original radio look with all the features of a modern sound system. He told me the only visible difference will be a small red LED indicator dot behind the tuning face numbers that indicates the radio is in FM mode. Has anyone else had this procedure done?
