1969 Barracuda Steering Column Interchange

You may not need a puller. The bearing isn't press fit.
Other than rust,
There is a tiny snap ring above the upper bearing. The ring groove develops a rolled up burr over time.
File away that little burr and the shaft should slide right out the bottom of the tube. Service manuals are free downloads. Even if your exact year model isn't , what is available will help.
