Steering wheel, column, and clutch pedal help

[1971 cheburban]

How exactly do you pull the steering wheel off, is there a special tool I need or what? If there is what's it called and can I get it from a local part store, an has anyone had any luck filling the cracks in your steering wheel with bondo or something like that, mines pretty bad shape but it's salvageable. And the clutch pedal assembly, is there any certain way the whole thing comes out easy, and also the three on the tree collar, someone said you can grind the area down where the shifter goes and make it smooth and maybe bondo it, has anybody had any luck with doing this, thanks everybody
