Just FYI Jon: The 55.2-59 GMC Radios (Blue Chip models) is sort of upside down from the Chevy TF radios. The bezel that sticks through the dash is VERY similar, but is on the bottom front of the radio and mounts in the rolled bottom edge of the dash that is GMC specific. I've attached the SAMS for the GMC radio.
'57 GMC 102, Original 347 V8, HydraMatic, 3.08 rear gear, added A/C, disk front brakes, HEI, AFB carb, '98 Honda Black Currant paint. T-boned and totaled 10/12 '52 GMC 152 Stake Bed, Original 228, SM420, added A/C, HEI, disk front brakes, '67 Chev 3.55 rear gear. Gets used as a real truck.
