These are the rear uprights. They need lower shaft hole boring and slotting with clamp screws drilling and tapping. Then the top would be drilled and milled out for upper heim and then you would have to decide on what bearings you were going to run and bore the hubs to suit..........then you would have to machine the offset and locate and drill caliper holes. Whew, I wonder why they didn't sell unmachined, but then you can't sell them machined unless it's to the customers hardware combo
