gaskets for steering column

As far as I know there are 3 gaskets/seals for the 65 early A steering column: the 2 white ones that are at the 2 floor plates and the black round seal that is actually installed on the column itself and actually seals the column to one of the floor plates. I don't think that seal is included in the firewall gasket set. FWIW, this black seal has to be installed on the column from the top after the column it disassembled. I forgot to install the seal when I rebuilt the column going in my Barracuda so had to disassemble it down to the bare tube!
