Won't Fire - Need Help!

Got a few minutes to squeeze in some garage time after "Back to School Night." Pulled the distributor, stuck the telescoping mirror into position, and "Voila!" No plug!!

I guess it's like putting together that kid's toy with a bag of parts... You get to the end of putting it together and there's a few parts left over....

In an effort to save money, figured I would install the freeze plugs on my own instead of paying my machine shop to do it like in past builds... So, ordered a bronze freeze plug kit from Mancini. There were (6) pieces left over, two small press-in plugs (For behind cam plate), two bronze 1.25" freeze plugs (looked all over, but couldn't find where those go), and two threaded plugs... Now I know where one goes, but where does the other one go? Is this another oil gallery plug I neglected to install??

"Secretly," that's why we're in this hobby... To learn new things, conquer new challenges, without screwing too many things up!!

Let's hope I can get this first plug installed through the distributor hole and not drop it down into the bottom of the engine...
