I found these two items, one in each door, when I had the windows out to replace the channel weatherstrip. They are kinda soft, so maybe when they were young they could have been foam like. I have not seen anything like it in any of the catalogs of door parts, so I do not know what they might be. Someone in interiors thought that maybe a PO put them between the glass and the door to keep the rattling down, but I talked to the PO who has had the vehicle since the mid-60's and he does not recall using anything like that. Though they would be a good fit as the length is about right. Could it be something that was used on the assembly line and just not removed? I am just curious.
