Bell housing/clutch cover?

[allflatblack]

I have a '69 C10 with a '83 350 mounted to a Muncie M21.
The bell housing is cast iron and is missing the cover for the bottom, which leaves the clutch and flywheel very exposed. I am not quite sure what year or model this bell housing is from, but would like to find a cover. Looking for "trans cover" or "bell housing cover shows me very little that looks similar to what I need. I assume that the M21 is off of a camaro-is that what i am looking for? Sort of answering my own question here-thanks for any pointers.
