The biggest difference is that '42 to early '45 was still a brazed frame while later '45 was a mostly electric welded frame. All the neck and rear axle plate die numbers are different on them as well.

Yes, the neck angle and all mounts, tabs, etc, are the same.

Factory blueprints put October 1944 as the beginning of Electric Welded frames.
