ebay seller "goodwoodcedar" had one for sale that no one bid on. You might look him up and see if he still has it.
But check the engine compartment for the rod. There's a lever attached to the bottom of the column just as the intermediate shaft connects. The rod attaches to that lever.
It's possible the switch could be unplugged or your backup lights could be burned out.
The rods come up on ebay every so often...and I believe the rods for the auto are different than the rods for the manual transmission.
I have a tilt column on my workbench. The key will pull when the lock is in any position. The key is worn down to the nub. The lock works ok, and everything within the column seems ok....so I think when the key is worn way down, it will pull out without being in the lock position.
