67-69 Steering columns

For automatic columns, 67 through some point in mid 68 have reverse lamp switch mounted on them. That switch moved to transmission mid 68.
If you look closely at the steering shafts, there is a tiny weld bead around it where the end piece with splines was put on. Which piece determined manual steering or power steering shaft. Aftermarket offers adapters for the shorter power steering shaft to reach and fit manual steering gear.
