The present invention is a retrofit apparatus for attachment to vertical milling machines. The invention generally comprises a main scale, a digital indicator, a mounting cover having a centrally located aperture for receiving the indicator and allowing vertical movement thereof, a plurality of hat clips and screws to attach the scale and indicator to the mounting cover, a rear mounting plate, a quill stop bar, a quill mount, and a rod. In operation, as the quill device of a milling machine is moved, the indicator slides up and down within the aperture and the indicator effectively and precisely measures the vertical displacement thereof. In an alterative embodiment of the invention, the retrofit apparatus comprises an aperture in the mounting cover wherein the aperture is substantially the same size as the indicator, and in operation only the scale moves while the indicator measures the vertical displacement of the quill.
