This is how the original rear shock mount was done in the Grand Cherokee. I was fortunate that the narrow section, that the threaded boss goes through, was the same width as the Willys frame. So the boss was cut out using a hole saw and holes drilled in the Willys frame on both sides. You can notice the offset so that the boss will be mounted at the same 8 degrees as it was originally.

   

I fully welded the boss in on both sides before final welding of the boxing plate to keep it from moving.

   

To prevent the frame from bending from all the welding on one side only, I tack welding both frames to some heavy wall RHS tubing. Additional tubes were added where the tubing was not central.

   

The welding was spaced out in sections so that heat was kept to a minimum. It was also kept balanced by welding both rails at the same point, both top and bottom flanges, left and right rails, so the pull while cooling would counter act each other.

   

The rails are now fully welded from one end to the other, 18 metres or 59', of weld! The weld was then dressed and sanded smooth. The edge has a sharper radius than the folded side as removed as little weld as possible to keep strength.
