I have two sets of Nickel Schaller Tuning Keys, with bushings and most of the screws. 20:1 CBS Fender Style. http://www.allparts.com/TK-0881-001-...ys_p_3704.html
These were purchased from AllParts and then sent off for the relic work. Each set was on a bass for about 3 months before I decided to go with 60's style long shaft reverse tuners. They work perfect, perform like new, and look awesome. Win, win, win.
$70 / set shipped.
