I removed the 3rd and cut a hole in the bottom of the housing, then replace the 3rd and used a tape and took a measurement. Once again I removed the 3rd and cut 11/2" out of the bottom, from the upper most side of the drain bung straight across the cover to the other side and down to the bottom of the 3rd flange with my plasma. I made a steel plate and welded it on at an 1/8" from the ring gear. The drain is now on the top of the housing for filling and pumping out the old lube. Then I made armor to place over the cover.
