Joe, Don't forget your "Model Year" for your plane is 1970. Your plane was made 32 down the line from mine....
Another tidbit. Your N number N5687G.... matches your ending S/N: 15071187
My plane (1970 K) is N5655G... and my S/N is: 15071155
Cessna apparently (in those years?) matched your N number ending with the airframe S/N. BTW. Our planes were made in the Summer of 1969 but they were
Model Year 1970 with solid headliner...etc (see list below). So FAA records always show when they issued the airworthiness certificate, but that is not the model year.
