I ground a 5mm weld prep around the outside edge of RU7 welded it completly, ground it flush then welded RU8 to both RU7 and the 5 inch tube. The edge of RU7 sits flush with the top of the tube and the holes in it are for clearance of the bolts, I'd put some spare M10 bolts in the tapped holes to stop any weld spatter going in and causing problems later.
