The basic steering column is the same for all 57-60 F-100-250-350. The column shift feature is an add-on which attaches via the upper hub and at a point below the cowl.
There is a plate that is spot welded into the upper hub which houses the turn lights, this plate secures the shift rod.. As I recall all of the dash column drops had the hole for the shift rod.
I have a 4 spd flr shift column and a three on the tree column... Both of them came out of '58-59 F100's which is the same as the '57's, however, It just might be that all of the '57's might not have had turn signals..
It is very easy to remove the shift rod from the column in favor of a floor shift, however, it is not so easy to add the shift rod into a non-column shift tube.
