Steering Column

[Ironhorse]

Changed my original 17" Saddle colored wheel to smaller '89 Suburban wheel. Got the horn working altho I apparently need to replace the horn itself. Sounds rather "anemic", changed the tone control on side of horn but still the sound sucks. Need to hit the parts yards and find a dual horn setup like I once had on a '69 Impala. That one made its' presence known when it sounded. Question I have is on the upper and lower column bearings. Have what seems to me as excessive "slop" in column and want to change the bearings. How much of a hassle is that and where can I get the bearings? Usuall parts houses or is that a GM part only? Any help is appreciated.
