vinyl window snap in

Question

This is off a Marvin window and Marvin doesn't make it any longer. I'm looking for something that I could modify. Don't mind the blue tape, that's holding it together.
The part that goes against the window is 3/4" but it could be a little less if need be.
The part that has the barbs for locking in the window is 9/16" of 5/8". Again I could modify.
There is a rain lip on it that I could make out of silicone caulk.
Please help, I'm desperate

Thanks for contacting us. It's hard to make out what you have from these photos. The break in the end profile is uneven, so we can't make an accurate read of the shape. That said, it looks like it uses a kind of kerf. Could you possibly get our 55-306 Andersen glazing bead to work? Look it over and let me know what you think.
