After the second breakage I thought I had it stacked nicely with rubber on both sided of the frame. So it went bolt, washer, rubber, frame, rubber, diff adapter from bottom to top. But when I got up under the rear end you could see that the bolts both snapped right where the threads ended in the adapter. So now we'll have 6 bolts holding it in instead of just the 4.
