Early A 2 Door Sedan Window Channel Sets (Not Cat Whiskers)

Hey, guys. I've seen a lot of posts about the felts that go along the bottom of the windows, and I just bought a set of Cat Whiskers from Herb's parts for those. I can't find the stuff that makes up the other three sides of the window anywhere though. Any ideas? It seems like a pretty basic C channel. Just don't know what to call it when I'm asking around.

Anyone else found a work-around for these and the tops of the quarter windows? Thanks!
