Early 28, Steering Column Upper Bearing

[Charles Reese]

Original beyond repair, have a Bratton repro.
(1) I don’t recall the original having a ‘collar’ machined at the steering wheel end (photo). (am concerned the control rods will set too high relative to the notches on the sector … rods are at plater so cannot verify this as a problem or not)
(2) should I file this ‘collar’ down so the bearing fits flush at the entrance to the column?

Photos of original or correct restoration would be greatly appreciated.
