Early A Body Steering Column Interchange?

The steering columns are the same, but the firewall plates seem to change every year. 66 has just one plate, 64/65 have 2, one larger plate that bolts to the kick, and one that bolts to the first one and acts to stabilize the tube a bit. If I’m not mistaken, the secondary plate has set screw that tightens it against the tube, it’s about 2” tall. Not sure if I have one to show, the 65 column I have is a 4 speed column, which also has a different secondary plate due to the hole for the clutch rod.
