My column is from a 65-68 olds I believe. I'm under the impression that that column was used in many different GM cars
from Chevys to Caddys. I found a part number for a 66 Chevelle that might interchange to your column.Auto zone Number sw 3027. Get all the info you can and find a parts store that has a car guy working there, not a make-
model-year guy. Good luck. The bearing should be easy being a GM.
