All the 64-66 Skylark columns are interchangeable. The ones from a 64-66 LeMans/GTO are the same as well. Finding a floor shift tilt is the challenge! Last couple I have seen on Ebay were in the $700 range. I have converted several column shift tilts to floor shift, so if you find one of them, I can make it into a floor shift for you for a fee and you won't ever be able to tell the difference.
