screen door replacement

[Southside]

My 1997 Jayco 1406 is just about finished with its renovation and one thing that is still left to do is replace the upper half of the screen door frame. Pins have broken off the bottom, it won't stay connected to the bottom half and generally falling apart. Finding a replacement screen door for this pop up has been unsuccessful. I do have a call into Hanna RV but no promises there, at least at the moment.

Does anyone know who sells screen door frame replacements? I don't seem to be able to buy one anywhere.

Also, if anyone has any other replacement ideas, I would love to hear them. Thanks ahead of time!
