Steering Column Rebuild

[AF_Chevy]

How hard and how expensive is it to rebuilt a steering column? Mine has some issues where when the truck is cold I have a really hard time getting the truck to shift from neutral back to reverse and park. Also I have a bit of play in the automatic shifter and want to get that fixed. Buying a new steering column is just out of my budget as I don't have $300-400 to just drop on a new one. Any advice, help, suggestions, or lessons learned would be very helpful. Thanks.
