What's the difference between the 2 and 4 door dart?

Hi
I have a 69 four door dart and need a new trunk seal and rear window seal. I've been looking online and see lots of parts available for 2 door cars but not as much for 4 door cars.
Can anyone give me a run down on what the difference is? (The main difference is very obvious!) Will a trunk seal from a 2 door car fit a four door car and same for rear window seal?
Thanks
