all that mumbo jumbo talk is how to center the clock spring, the rest is just like i said pretty much.
dont sweat it. i see no need to change the column.
if you get your clock spring at the junk yard make sure the wheels are straight if at all possible then take the clock spring out. if not you need to center it. its not hard, i did it to mine.
the simple way to explain it is.
theres a button on it, push it in the center will now spin, slowly turn it one way till it stops. now count how many full turns it takes to get to the other side. mine was 7 iirc. turned it back 3 1/2 turns, done. put it on the shaft. be genital with it, and try to force it any further then it wants to go or you will break it.
