I believe RE7A-L was the original leading plug, and the RE7C-L is the newer leading plug of a somewhat different design as I understand it. Check with Rosenthal or Trussville to see if they have the newer leading plug.

How about having a look at the Specifications page in your owner's manual as a starting point?
