Valiant V200 wagon - tailgate window weatherstripping

I know - unobtanium. I know that Joe Suchy has been looking for NOS or a piece in decent shape, from which he can reproduce; but no such luck. (I did buy the B Body lower weatherstripping from Joe, I adapt as others here have done.)

What have folks done to replace? Is there anything that comes close and can be adapted, from Quirey, Steele, etc.?
