Upper Steering Column Bearing

'65 Barracuda...
I have a Gritty, Squeaky Noise at the Steering Wheel on my 3-on-the-Tree Column.
I'm Doing a 3-Speed to 4-Speed Conversion this year So,
I bought a Floor Shift Column and it has the same Bad Bearing in it...
Where do I source this Bearing and What is it called?
