Here's a picture of the 7 tooth steering. The long steering shaft is adjusted by removing shims under the bottom end plate held on by 4 bolts. The column and box are one piece.
The 2 tooth steering has a clamp, at the upper end of the gear box, which holds the column to the gear box. Just below the clamp is an adjusment bolt and lock nut, which is used to adjust the end play. DO NOT turn the bolt down tight as it can crack the bearing race. Be sure the clamping bolt is loosened before trying to adjust end play.
Here is a 2 tooth steering box with some odd grease fitting in place of the original..
