My recent wheeling adventure exposed a potential weak point in my 1981 FJ40 underbody. I got myself hungup HARD on a rock right up on my inspection cover and my oil pan. I dented the oil pan and crushed the inspection cover so bad I was throwing sparks and had to peal the cover open to clear the flywheel. There isn't much space in the area to mount a skid plate that wouldn't interfere with the front DS. So, has anyone seen or built a heavy duty (think ruffstuff style diff cover) inspection cover for their rig?
