The funny thing about the F is that was the year they produced the most 150s, yet interior parts are the hardest to find for that model.
That's because it was a bit of a hybrid year between old and new. It was the first year they went to the larger baggage compartment. They used the same plastic for the front of the baggage compartment, and specified new pieces for the new back half. The next year Cessna came up with 1-piece plastic for the sidewalls of the baggage area and used that design until the end.
The other difference is the doors. Again, this year was the first for the larger doors. But these doors, though outwardly similar, are different than all later 150s in that they don't bow outward to give more room in the cabin.
The instrument panel retains the older 'rounded cowl' design. The very next year they went to the 'straight' panel with a six-pack arrangement. Getting plastic for any round-cowl plane is difficult.
In some ways it's simultaneously the most common and least common 150 out there.
