Steering box cracked frame repair?

Drill ends of crack. V groove crack. Weld and grind flat where crack is. Fishplate the frame with 3/16 plate that is one piece as wide as the frame. NO SPLICES Ends of plate should not be cut square. You want large radiuses not sharp corners. This reduces flex cracking of the frame at the ends of the plate.

To eliminate this in the future I would suggest a steering box sector shaft brace. If you have skills to fix the crack then you should be able to fabricate the steering box brace. To make the job easier Solo Motorsports has made a rod end adapter to replace the pitman arm retaining nut. I wouldn't use the Nylock pictured. Red Loctite would be much better.

The plate should be on the outside. Using angle iron is not a good idea. You want the face plate and wrap under to be all one piece. You only going to move the box 3/16". You will only have to lengthen the drag link. There should be plenty of adjustment in the link ends.
