Jack length need to be considered. If your replacements do not quite fit, remove the jack support flanges from the top ones and place them in the center. This way, the odd jacks will be not used as much. But trim the jacks to length if needed. For transplanting parts from the top end, take from A# or G# rather than B & C. They are played even less frequently, even by compulsive key pressers. -- Regards, Jon Page
