welp, i went to go pull the old MC out of the wall and....it will not budge.
I disconnected the outlet it was attached to, and looked for any lockrings or MC connectors to the metal outlet box...nothing....so i head into the basement, and grab on to the 8' section, put some weight on it....nothing....not even an inch.
The outlet is about 5" off of the floor, and from the basement, i can see the subfloor, so that means im trying to pull through maybe 7" of MC....
I can see where it goes into the cinderblock from the basement...theres no way they would have wired the outlets *before* they finished building the walls would they?
do i have any options? I put some serious torque on it, and not an inch....although the MC started to stretch at the joints.....arghh.
