I am pretty sure the weather strip is the same for all of the years.
Ford did not make changes in trucks as much as they did cars. This was because buyers bought trucks for a job. And bought cars to feel a certain way when driving. Cars were changed a lot to meet the demand of a new feeling or ride when out on the street. A truck was needed to do a job and the job didn't matter if there was a lot of chrome or bare sided.
With that said parts for lower production vehicles are not as plentiful. Good luck!!!
