The outer tube is original. It is shortened and has a plate welded on the end (like a large washer). I made the top housing that holds the bearing out of aluminum. It slides over the factory column tube and locks with a bolt. It's shown in the 2nd pic, it's painted and installed on the tube in the 3rd pic. Also the shaft bearing (generic 3/4" ball bearing) is mounted in the aluminum adapter. It is the only bearing, no bearing at the bottom of the tube. Shaft is 3/4" x .090" moly.
