Other window sizes? 22' Argosy

[Rollinstudio]

Hello everyone.
Are there any other sizes other then these ones I am currently seeing for an 1973 22' Argosy?
18.5" x 22"
30.5" x 22"
40.5" x 22"

We want to enlarge the awning door/side window from the 18.5 that is in there. It seems without cutting into the "ribs" we can't fit 2x30.5 which is what we would have wanted.

so somewhere around 26" or 28" would be ideal.

Those are the standard Airstream/Argosy window sizes. Anything else will have to be custom made $$$$. Be very careful changing sizes, as you might compromize the body integrity.
