Technical '41 & Later Ford Front Seat Dimensions

Regarding '41 and later Ford Coupes:
Can anyone shed some light on which year front seats are (roughly) the same width.
I would think the '41-'48 fords all share the same front seat width, with a straight bench in the biz coupes/fordor cars, and folding front benches in the opera coupes, 2 door sedans, and club coupes.
Are the '49-'51 shoebox front benches the same general size?
For what its worth I am looking for a split folding bench for my 46 Business Coupe along with a pair of rear opera seats.
Cheers
Ryan
