Am I missing a part??

So I got under the car to better access the fuel filter a few days ago, and eventually got to assessing the rest of the under-car area, including the dented-up oil pan (will need a new one, probably toss it on with the next oil change). I noticed that my bell housing was "open..." Literally, I could stick my hand up into it and feel the flywheel and such....

Am I missing a cover or something? If so, does anyone happen to have a spare, possibly with the hardware?


Thanks,
