What locking tuners are direct drop-ins for Grover Full-size Rotomatics?

And by direct drop-ins I mean that I also need the little screw hole on the lip to line up perfectly. Anyone know? I have tried the Grover 106 series locking tuners and they were a no-go as the screw hole on the lip did not line up.

Just curious - why would you want to replace the rotomatics? Those are the best tuners I've ever found.

Grover makes two different kinds of locking tuners based on that size. One is self locking and the other has a thumb wheel in the back like Sperzels.

The ones with the wheel don't line up exactly either, but they worked out okay anyway. I just kind of manhandled the screw into the same hole. It holds fine and no binding at the post or anything of the sort.
