To make the needed bends in the boxing plate to follow the frame shape, I just used a blunted brickies bolster and hit it between two sections of steel. Can use a piece of channel too.
The bends are following the frame shape quite well.
Can see in this shot how the edge of the cross member mount comes through the boxing plate where it will be welded and then ground smooth.
Also shows the only joint in the whole boxing plate. This shape increases the weld area and has the least amount of stress rises.
All plated up. Also seen is the front cradle mounts coming though and flush with the boxing plate, ready to be welded and then ground smooth.
This is part of the Grand Cherokee frame that has the rear shock mount in it. I was fortunate that the narrow section it sits in was similar to the width of the Willys frame. When I laid out the width of the Willys frame, I made sure it would run exactly along where this mount needed to be.
This is the hole for the shock mount in the Willys frame drilled at an 8* angle to match how it was in the Grand Cherokee.
Original shock mount was cut free with a hole saw and then welded in to the frame on both sides. Another piece of metal will be formed to support the other side of the shock eye so it will be in a double shear arrangement like the original setup.
Also finished welding in the other end of the swaybar mount.
