Randy,
The 66 to 70 B-Body wagon door seals are the same for the various year applications for the four door wagon 66 to 70. There is a difference in the 66 to 67 four door sedans as compared to the wagon back doors. The window felts are different for the wagons as compared to the four door sedan applications as well. The difference is in the rear door felts. So make sure that your vendor of choice is able to offer that as many believe that they are the same. The rear tailgate seals are still under development. The window felt for the rear tailgate is something that we provide, but only make them up on purchase as there is very limited demand for the product. The glass channel run is available as well, but no quarter glass seals are available at this time and I do not know of anyone even working on that project. Check out our website, but it would be best to just contact us directly as there are some peculiarities of these different year models to make sure you get what you are looking for.
Thanks,
Richard
