Next you will need to work on your steering column. If you’re using a stock column, cut the shaft and remove the stock steering box. The end of the shaft must be machined to 7/8-inch diameter to fit the Flaming River universal joint provided, and installing the brass bushing in the bottom finishes the column. This Jeep was fitted with a DJ column that didn’t need cutting and has a splined shaft that will require a different universal joint. Advanced Adapters also provides the firewall plate, which must be welded into place to secure the lower portion of the steering column.
