I'm a fan of the Planet Waves self-clipping tuners myself for locking tuner applications. Most locking tuners are going to require widening the post holes though as Jaguars use Kluson style machines with press-fit bushings stock.
I use my CIJ with the stock tuners and have no issues, but when the tuners on my CIJ Jaguar wear out I plan to just swap em' with Kluson Tone Pros as I really like those, they are non-locking though, and come in press-fit bushing and Schaller style bushing variants.
