John held the column straight inside the cab while I tacked the piece of tubing to the firewall. I then removed the column to finish welding so I would not fuse the column to the piece of tubing. Then a Grade 8 bolt was used to crimp down the exposed piece of tubing to crimp down on the column. That sucker was tight after the bolt was tightened. Make sure install the top CPP drop-down bracket like the column in the above photos.
