Talked with my local machinist and he can press out the old throwout bearing and press in the new one when I get it.
Removed the black plug/seal. Turns out it is metal, not plastic. Was loose enough that when I touched it with a small flathead screwdriver, it slid back in its hole about an 1/8 of an inch. Put some duct tape on it and it pulled right out. Even though you can see someone applied some kind of sealant on the outside surface... it was very minimal and the seal is very loose in the hole. Needs a more substantial bead around the edge to make it seal oil.
Waiting to hear back from my dealer on parts.
