Did your upper seal have metal in it? I bought some for my 59 but I couldn’t get it to bend right and fit good into the door. Mine had metal on the sides.
where did you buy your window track seals. there are some really crappy reproductions out there's far as I can tell the tracks are very bendable and have like metal mesh backing.i still have one old one out another door I could do a short video on what it looks like.and you can have that one if you want it.
