Bearings for Steering Column

[Orion 762]

I have a '71 Cheyenne, and got into rewiring the steering column. Once apart, I noticed the old bearing are about shot (both bearings at top and bottom of column shaft).

Any hints on where to get new bearings? Autozone and O'Reilys can't "look these up", and the local Chevy parts shop only sells the "whole rebuild kit".

Just need the bearings. Are there "other year/models" that use the same bearings?

Any help is appreciated.
