1955 Fords had a two spoke flat steering wheel.
IIRC, for '56 some/most/all (?) were changed to a three spoke dished steering wheel.
A steering column from the same model '55/'56 would be shorter in '56 for the different depth of the dished wheel.
I'm not positive about the Fairlane's, but a quick look at the steering wheel should tell you, or measure from the dash mount to the top of the column.
