Steering column ?

[mprat]

Was trying to figure out how to remove the lower shaft out of my steering column, its on a 67 chevelle, I know these are made to collapse in an accident the way they are made. But wondering if anyone had ever removed one of these.. I tried to seperate it but it looks like its in there really good. I did try beating on it while in a vice but figured I better quit and ask befor I damage something....
