the little plate that bridges the legs, place that in your woodworking vice with half its length sticking out, give it a tap with your lignum vitae mallet so you have a slight bend in its middle, pass the U-bolt (with the kinked plate, covered by a small section of tyre inner tube) up through chrome rack and through your top plate- screw nuts down (a drop of loctite threadlock) trim off threaded section with a dremmel, get the biggest cable ties you can find and use them also
