I think I figured it out hipshot makes three different bushings. The ones that came with it were the smaller ones around 15mm. I just ordered the size in the middle the 17mm. They also make one for 18mm. I will feel a lot better getting the right one. We shall see. You would think for the price they would include at least two different sizes.
Due to the variation in peg-head bore size on basses with 1/2" post sized tuners Hipshot offers 3 different bushing diameters for their Ultralight tuners and Ultralight Detuners.
There are three different bushing sizes available for Ultralight tuning keys.
.618" 15.7mm
.660" 16.7mm
.700" 17.7mm
0.618"(15.7mm) is intended for a smaller bore size of 16mm. Examples of basses that utilize this particular bushing include Fender U.S.A, Lakland Skyline or any basses built with the Hipshot Lic. Ultralight 1/2" tuning keys.
0.660"(16.7mm) is the standard bushing size that comes supplied with the US made Ultralight tuning keys. Fits many basses with 17 - 17.5mm bore hole.
0.700"(17.7mm) is intended for the larger bore hold found on many Made In Mexico Fender basses, or any bass that utilizes a 18mm bore hole.
