40 Tudor Quarter Window Help needed.

[klawockvet]

My 40 Tudor had a rusty mangled tin strip that covered the back of the B pillar. My 47 Tudor appears to have something similar that is covered with a canvas type of material. The piece is held on with the one screw that holds the top of the front window channel. The piece keeps the front of the window from touching the B pillar when the window is rolled up. Any help with the name of the piece, and where to find it would be appreciated.
