My patio screen door is 77 in. high with an opening for the bug flap (59-054) of 1/4 in. I presume your bug flap will snap in and expand to hold the flap on the door.

It is possible, but it is hard to say without actually trying it in your patio screen door. Look at your vinyl bug flap and send us the measurements of the width and the part that holds it into the patio door. Reply to this discussion with a photo.
