Basic, probably dumb question

Looking at the pic below, I'm thinking that this is just a flexplate for an automatic-equipped vehicle, right? I believe that since I'll be using a T-56, I'll need to replace this piece with a flywheel, & won't this anymore, but I'd feel better if I could get that confirmed.

(Sorry guys, but I just haven't done much at all with anything related to transmissions...)

It looks like I'll need to remove it either way so that I can align the oil pan correctly, but I'd like to know for sure whether or not I'll need to re-install it... Thanks.
Thanks again guys.
Thanks again guys.
