Here are the picture I have of the project.
Front Hanger with spacer I made to fill the gap.
Spacer welded to hanger, this spacer is so there is no space in between the hanger and the frame and the bottom of the fame is not smooth, it is lower on the ends.
Hanger welded in place with supplied gussets and extra "Elvota" fix gussets.
Frame plasma cut, tube inserted and jigs holding them in place.
By tack welding the tube with the jig in place you get a perfect alignment, the down side is that you have to destroy them to get the off. No problem as every kit comes with a set of jigs.
