Considering the makes and models serviced and then all the colors and trim options the factories offered yarns ago, they can not possibly keep everything on the shelf. I think it was Chrysler had something like 25 or 30 steering columns in inventory. Might have had two or three in each warehouse. Some bean counter did a cost analysis and they reduced to I think it was 5 for colors. Then you put model specific steering wheel or center pad on. Differences in length were taken up by a handfull of intermediate shafts.
