Steering column rebuild

[golden boy]

My 67 Barracuda has a lot of slack In the upper steering column attachment . Can't keep a turn signal switch in it. Appears to have a fastener missing under turn signal switch. I want to take it out and rebuild/ fix this. Can the bearing/ parts be purchased easily(bearing house, dealer,etc) to do this? Has any one done this? Its really annoying.

The bearings are special application. The upper bearing has a rubber isolator covering its outer race. They are available though, Ebay maybe ? I forget.
If its column shift some of the hardware in there is special too. Good used nuts and screws should be obtainable.
