Doors and Windows - retractable storm door repair?

I have an emco forever door which has both a glass and a screen panel that each slide into the lower half of the door. Unfortunately, the frame for the screen is bent.

Is there an easy way to replace the screen frame? It looks like you'd have to open up the door cavity! At that point it seems easier to just buy a new, replacement storm door - especially since the closing latch hardware on the existing door is already broken.

Has anyone had any experience?

Which model is it? Emco has pretty good instructions on most of their models, but there are a couple that you need to know a trick or 2.

Is it a very thick (like 1 1/2") "plastic" door? With 2 raised panels at the bottom? OR with a X pattern on the bottom and a scalloped design around the glass?

I think it's

Is it a very thick (like 1 1/2") "plastic" door? With 2 raised panels at the bottom?

It's model number 1249942 if that helps, and I would date it at maybe 15-20 years old?

Is it this one? https://www.stormdoors.com/productline/door.cfm?seriesID=5039&doorID=24

Disregard the brass plate in the middle, if you don't have it..that was an option. There may be a raised outline for the plate though.

That number is probably the registration number...though they may have changed their designations in 15 yrs.
