Hey Jeff, I recently put the Gotoh locking on my LP, the original bushings
were too small and I had to get the larger ones. In my case, the larger bushing
fit great and the tuners are very stable. I'd go with the bushings and if the don't seem
right (enter OCD) than its only $10 you lost. Love the Gotoh btw. Good luck.
Peace,
Darrin
