I've searched far an wide and can no locate these parts;
1978-1990 Side Loading Door, Rear weatherstrip 4354112

1978-1990 Side Loading Door, Front weatherstrip 4354113

1978-1990 Rear Loading Door, Right weatherstrip 4354114

1978-1990 Rear Loading Door, Left weatherstrip 4354115

I have found some for 77' and plenty for chevy vans, and It isn't possible to use universals (I tried),

Any idea?
