A-Body Front Floor Pan Install Question

Will a full front section floor pan for a 69 Dart (2-Door non-post car) fit through the door opening with the rear glass rolled down? The dash and steering column will still be in place. Someone mentioned on certain vehicles the full floor pans need to be cut to fit through the openings. I'm guessing the install issue occurs on post cars 4-door vehicles?

Steering column may be an issue, but the one I did had the dash and column out, so it slid right in.
