Use a socket to support the plastic threaded base - a deep 3/8" drive 5/8' is about right. This allows the threaded rod to go through the socket driver hole. Use a hammer to drive the rod out of the base. Use some WD-40. I have taken a lot of these out of the base this way.

I tried a socket and it looks like a good support. I also soaked the threaded rod in WD-40 all night. I still was unable to budge it this morning (using a hammer on the inside top of the post). There isn't enough of the rod, on the inside of the capacitor to be able to drill a small hole and use a bolt. On the inside of the base it looks like there is a round washer like device attached to the threaded terminal. By the way, I have a second copper Mershon and it does not have a nut embedded in the bottom of the base. Both capacitors have the very same part number stamped on the top. I am going to try to open that one and see if there is a difference between the two. Thanks guys.
