I was working on a mandolin that had the key holes drilled to a larger size than my bushings were. I searched on line at stewmac and found the size that I needed and bought them. They were just what I needed. I had to buy 2 packs to get enough to do the job. I wish they would pack 8 to a pack. They were very good quality and done the job for me. Thanks StewMac.

I've been using these as my go-to for all my Kluson tuner updates. I know they fit! no re-drilling.

These are the correct size for the holes in the mighty mite aftermarket necks, when fitting vintage style tuners. fit tight and look good!

These were absolutely perfect to add my set of Grover Sta-Tites to my build. I would suggest leaving them out until you have properly finished buffing and polishing the guitar, I was a bit too aggressive and took the gold off mine :- Great product! Great staff!

used on my mighty mite reverse neck and there was still a little bit of play. was hoping for a tight fit as described by some other customers, but no dice here. still the best thing i've found so far, though.

Great product, so easy to fit vintage tuners to a modern headstock. They dont look oversized or out of place.I used them on a relic project recently.

I bought two sets of 10.5mm bushings to convert from 3/8" mounting holes in two Mighty Mite Stratocaster style headstocks to mount 1/4" split shaft Kluson Tuners and the bushings worked PERFECT! They can be pressed in by hand not requiring the additional purchase of a hand arbor press and they still fit snug enough to hold well. NOW- About shipping...PERFECT!!! How did the world ever get along before Stewart MacDonald?

The 10.5 bushings were perfect for my headstock and more importantly, are the perfect flange diameter so that the view from the front is pleasing and in proportion to both the tuner stem and the round string retainer (on my Telecaster).

Excellent bushings , fits perfectly.

Got them in without using force , still a tight fit.

So I picked a cheap partscaster that would not stay in tune, when i examined the bushings on the vintage type tuners they had been wrapped in paper to fit the late model neck! These bushings solved the problem instantly!
