Door seals?

[Rufas]

I have a 1970 GMC with the push on doors seals and my doors are extremely difficult to close. The doors close fine without the seals installed. 'IF' I remember correctly I got the seals from Brothers Trucks before Holley took over. I finished the truck 5 years ago, but don't drive it often, so I have just been living with it.

I've spent the last few hours researching 'door seals' here on this site. There are lots of threads that are years old. There are so many threads about glue on, push on, Honda Civic doors seals (I have found new seals), and Dodge Dakota doors seals.

Things change over time. Who has had good luck with getting doors to shut without slamming and what seals did you use?
