Matt,
I believe that you are going to find that you are going to have to check each airplane on an individual basis.
Seat change? Supposedly the seat change happened in 1970, Matt. But I do not believe that the seats have actually been lowered." Cessna put less cushion in later seats to make them appear lower. And to give more room. So depending on if the airplane still has the original upholstery or not? Or even the original seats? In 1972 the seat tracks were lengthened by two inches. But the seat is primarily restricted from moving back by the step up to the baggage compartment.
Empty weight? That depends on accessories and options installed on the aircraft, more then the year itself.
Other changes that you didn't mention? In 1967 is when Cessna bowed the doors. Flat or tube gear? Short or tall tail? Fuses or all circuit breakers? Flap switch?.......................
We have owned a 1970 and a 1975. Though I actually prefer the 1967 to 1970 models. We now fly the 1975. Why? Because it was the best value at the time. In reality, the options really don't make that much of a difference. At least to us. They fly equally well, (ah? Except the taller tail and longer dorsal? But I have learned to live with that!)
So, unless you just must have a particular option. May I suggest that it may be better to concentrate on the individual airplane rather then restricting your self to any particular year?
Enjoy your search, Matt.
