This unit is one of the nicest and strongest support brackets I have seen for the Model T steering column and it's made of heavy cast iron. It's installed on our 15 touring car. If you notice one side has a longer curled finger that wraps around the column on the passengers side. You have to clip the longer curled finger under the column and then rotate it toward the drivers side which locks it to the column. The clamp on the back locks the unit to the lip of the cowl. This unit is a lot more rigid then a similar thin APCO accessory bracket. An added benefit is that no holes need to be drilled to mount the unit so the car can be returned to the way Henry made it easily.
As A side note I took the unit off our car to take some close up photos and misplaced it. I spent untold hours tearing the heck out of the house and garage for the last nine months with no luck finding it until yesterday. I happened to look down while climbing up to reach something on a top shelf and there it was. I had all but given up looking for it thinking I might have left it laying on the running board and drove off and had it fall off on the road some where. This getting old stuff is a real^%&*^%!!
