This is all ground away
The underside of the frame rail
Part of the extraction process required the use of a air chisel. This put some valleys in the frame rail. To correct this, some stitch welds were put on the rails to fill in the gaps and provide a level surface for the new tower.
More welds on the bottom
The top is then ground down to a smooth surface
As is the bottom
Here is the comparison of the original tower and the replacement tower
The welding surfaces of the replacement tower are cleared of rust to promote a clean weld
On the underside as well
The replacement is fit into place and the welding process begins
Backside view
Welding on the front is complete
Here is the view from the wheel well. The welds will be ground down to match the factory installation
