[EDIT - Please disregard my idiotic subject for this thread .... I mean to ask if Crown Imperial is interchangeable with Verve.] There's a Price Pfister 2-handle Crown Imperial set in my shower stall (installed around 1970 if that matters). I'm thinking about a rebuild kit to replace all of the replaceable parts and trim, but I can only find a 3-handle Crown Imperial kit, including diverter, and it's kind of expensive. Can I use a Verve 2-handle kit instead?
