CB makes more sense, since CA was auto tilt.
CB was the same for all three years, but I can't cross broadcast codes into part numbers.
TN 7803779 - 67 floor shift (non-tilt)
CB 67 & 68 floor shift with tilt wheel
CN 7803777 - 68 floor shift (non-tilt)
TK 7804300 - 69 floor shift (non-tilt)
TI 7808537 - 69 auto column shift (non-tilt)
CA 69 auto column shift with tilt
CB 7808154 - 68 & 69 floor shift with tilt wheel
