Bob, actually that isn't quite so. The 1941 is an oddball by itself. From what I have read, it had some designs of the 1939 and some of the '41 carried over to the '42.
I have since seen a "blueprint" page from a frame alignment book showing the 1941 which seems to have a different x-member closer in looks to the '39 (though I have seen photos and the 41 looks sort of like the 42), a different crossmember above the rear axle, and the rear of the frame is like 3-inches narrower than the '46-'48.
That is why I would like to see an "official" original frame diagram with dimensions from a Ford Service Manual covering the 1941-1942 models - for both years to validate what I see in the blueprint frame chart or dispel it.
Someone out there must have a copy of the manual or a Chilton's Motors Frame and Body Crash Book covering those years showing the frame diagrams?
