I do not see a model number or any number on these doors
If you're talking about Vista doors from Anthony International, Here's an install sheet including regulating door alignment and tension: https://www.anthonyintl.com/docs/default-source/service-support-documents/Vista_C_Installation.pdf?sfvrsn=0
Know also that if your doors are old, it's possible they've sustained damage over a long service life.
I hope this helps!
