steering column upper bearing

I am rebuilding the steering column ('69 road runner), I need to replace the upper column housing bearing. Chrysler had a special tool for it that bolted in the three holes for the metal retaining ring under the turn signal switch, pulled the housing with the bearing upwards from the top. Anyone know where to get the tool, or another method of removal?? Thanks.

Maybe a slide hammer with a creative attachment?

I used all-thread in the three holes for the bearing plate and used a 3-way steering wheel puller.
