I don't think anyone sells a "kit" to re-build a '62 Olds steering column.
You will have to source out the parts individually.
There really isn't too much to re-build in this column.
Your column would be similar to the column shown in the upper illustration below.
The Starfire column is even simpler than the one illustrated, because it doesn't have a shift tube or lever.
The only parts that wear out are the upper and lower bearings, the turn signal actuator, and the horn contact.
The bearings ( # 6.521 in the illustration ) carry GM # 5675777 ( upper ) and # 5674067 ( lower ).
The turn signal actuator (# 2.895 ) carries GM # 5674991
The horn contact (not shown ) is GM # 766648 .
As always, Google and E-Bay are your friends.
Good luck.
