Putting that plate on the side of the frame about sheared my thumb off. I added an 11 x 3 x 10' X 1/4" plate and my jack shifted, wedging the plate between the frame, my hand and the tire. Anyway....the plate would help on a dump but it's probably too late for you. Just the area where the rear trunion was attached, had lost more than 50% of its strength from rust where the plate joins, is riveted, on my A3. Look for rust swelling on the frame behind that trunion plate.
