Only difference between a 71 and a 69 radio is that the radio dial lamp on the 71 is wired directly to the dash lamp circuit, so that the dial is lit (and can be dimmed) by the dash light switch and is only lit when the dash lights are on, while the 69's are wired off the 12V power supply and is lit when the radio is on, and not lit when the radio is off wheather the dash lights are on or not. That and the different shape of the heat sink on the rear of the AM/FM radios, square in 71, angled in 69. It will still fit.
