Not much, i have a 77 with a tilt/tele column, and it took just a phillips and flat screwdriver, thats it...
Just make sure you disconnect your battery, i didn't at first and shocked myself a few times. :W
Use a flat blade screwdriver with tape wrapped around it to pop off your horn button.
Underneath that there are 3 screws that hold the horn button assembly, remove that.
Then on my car there was a butterfly screw and 2 small phillips head screws that held the tilt/tele adjuster in place(don't know what you'll have)
then i think there are 8 screws that hold the actual wheel in place.
Should take no more than 30 mins, really easy job.
