1939 vs 1941 front bench

[1963turnerjohn]

Can anyone tell me the difference in size for a 1939 vs a 1941 Ford split bench seat? And if anyone knows - if a 39 bench is fit in a 41 - is it too small in side to side width?

If I use the 39 bench - it will be upholstered with custom high grade vinyl - so no worries about original spec, though I do want it to look like it fits the cars interior ( and not look too small )

Thanks,
John
