36" Hitch Extension for 2" Receiver - Are they Made?

So is the receiver drilled incorrectly or the extension tube drilled crooked? I looked at the picture and cannot figure which is faulty. As others posted, each tube can be inserted into the receiver individually and pinned, then the clamps are applied. Once fully assembled and tightened, there is no reason to touch the clamps and the double truss can be installed or removed as a complete assembly.
