I started by taking measurements and checked some angled with an angle finder. Then I drilled out all of the spot welds on the mounts. Next I welded a piece of tube steel from mount to mount, to tie them together. Then I welded pieces of angle iron to the Frame 10.5" back from the top of the mount as a reference for moving them back. After that I chided of the mounts that were now just held on basically by seam sealer.
