1969 Mustang front window glass channel and rubber

[MD69Boss]

Good morning, looking for a source for the stainless steel channel and rubber seal that glues to the back of the window glass, passenger window specifically. Prefer NOS, unless someone can vouch for the quality of a vendor...
I looked at Dead Nuts On website and don't see where they reproduce this.
Here is a photo of the channel without the rubber seal:

Any leads are appreciated...
