Marine Trader window spline

[Maravilla1]

We have a 1988 Marine Trader and the spline (2 types) that seal the window and seal the track where the screws hold the frame to the hull is falling out. Does someone know where I can find replacement spline? One type is a single edge that goes out onto the window face with a bayonet piece that locks into the frame. The second type is a rounded center with two smaller locking edges, one on each side. Thank you!

It always helps to include some good quality photos.
