Not positive on if this would work, but what I can tell you that if it did work, it will not just be a verbatim fit for the current tailpiece. They are two completely different designs and I would imagine that some additional routing would be involved in order to make a stop tailpiece work on a Mustang bridge. Maybe someone such as HNB or redman can pitch in some advice here, as I'm sure they know much more about the logistics of this type of mod.
