Thanks all. SilverBeast, I have the upper column cast aluminum piece, but... in your picture where the ignition key is there are two bolt heads shown on a flat plate. That flat plate, #16 in the exploded view, shows two bolt holes and a third larger one for column past thru. The bolts I have in the clamp are the same as shown in your picture. So I think this clamp just helps support the ignition stalk. Strange that the clamp is not shown in the exploded view, but it all bolts up. Seems some TC/TCS items just didn't make it into the exploded views?
