Jeremy,
Is your column the one with the torque screw that locks the cylinder in place? or the one with the small metal clip style contact?
There are two styles. The one with the small metal contact is a PITA.....You need those very small screwdrivers used on eye glasses, at least I did.
Don't bitch it up, you'll be quite mad at yourself later if you do. It's hard to find a decent column for under $300....New = $600+
