1998 Ford Mustang GT Engine Block Drain Plug Or Plugs

Where could I find the 2 engine block drain plugs at (assuming there are 2)? I thought I found one under a freeze plug that had a 5/8" head on it, but I thought the drain plugs were more like the one on the differential. Might someone enlighten me as to where the engine block drain plug or plugs are and how to remove them? Maybe even provide a link to pictures of a 4.6 showing where they are and what they look like? I thought they were suppose to have a green stripe on them.

Thanks In Advance,
