Help w/ Schaller Locking Tuners

[GuyaGuy]

apparently i'm the world's worst internet searcher cuz i can't find instructions on installing the Fender Schaller Locking Tuners. got em used, no info. i believe they're installed to incline so string trees aren't neccessary. they're the ones with III on the back.
can anyone help?

If they are anything like my sperzels they are installed at an angle. The shortest one being the high E and the tallest being the low E. Other than that what problem are you having? Peace Damian
