Frame fix for a 2002 Dodge 2500 van

I have a good running van and it has the typical rusted broken frame by the steering box. I see there are kits you can buy to repair the frame, anyone do it? If so, what kit did you use?

The steering box mount was all rotted out on my 98.5 2500 truck, and I just cut out the rotten parts and rewelded in with 3/16" plate. I used tube spacers between the rails like the factory so the frame wouldn't crush when tightening back up the steering box. No pics of finished product, but one with starting to cut the rot out.
