I am breaking down both doors on my 1976 280z as I prepare for media blasting. The first part was this small roller connected to a bracket that was slid inside the outer stainless door trim. There was only one on the passenger door, none on the driver's door:
The other thing I was wondering about is these pieces that were on the outside corners of the doors. I'm sure at one point they were pliable rubber, but now they are rock hard:
Any help identifying these parts is appreciated.
Thanks
