Im trying to find out the technical name for the stuff that is on the edge of the door that keeps the rain out of the door... and keeps the window tight. I was looking on JC whitney, but Im not sure what I am looking for exactly. Anyone have a link or an exact name?

 

check lmctruck.com they have those parts listed, you can find the name there

 

Try NAPD National Parts Depot. They should have it. I think thats where I got mine from. I think they are called door beltline wheatherstrip. I got all 4 reproduction ones. All 4 are different. The inner R may look like the outer L but the clips are in different loacations.
