Well Gregg, since no one has given you any reply, I will take a stab...
My 68 250S has play as well, so I blindly ordered two parts from aftermarket, thinking that these are the most commonly worn out parts. On your marvelous scan here, I think that they are part #s 53 and 51.
However, you are indicating play at the bottom of the column, and you will probably need the appropriate parts from a dealer.

From the drawing, it looks fairly straight-forward, but kind of a PITA.

Please let us all know what you did. A lot of people read these posts, but don't actually respond-but everyone learns a little!
