It was asked if the thumbwheels were included;
Here is the package;
Bridge, one piece stainless thumbwheels and inserts.
The thumbwheels are spring loaded which is a nice overkill touch (in my opinion)
Unless some one was using this for a new build, the inserts would not be needed.
The thumbwheels thread right into your nashville inserts
Ps. sorry for the photos I am a guitar builder not a photo pro
