Could someone please tell me what the diameter of the heatsink plates are for an old original rectifier (selinium iron disk type) that would be on a Mercury mark 55E? If I can't locate an old rectifier to take apart, I will cut out some aluminum disks, paint and drill them, and mount them on a full-wave bridge rectifier to achieve a more authentic look. I ordered some from Mouser Electronics (20-Amp, 50 Volt, Mouser # 583-Rs2001M) that are flat in a SIM package (leads all sticking out flat on one side). These are flat so that a person can sandwich them between plates.
