New old stock, Cycle Country Electrix Shift Conversion kit. I believe the button, wiring and controller are able to be used on most all models of ATVs. The mounting and actual shifter is designed for Suzuki LTF 300 4x4 (99), LT 4X4 250 (99), and LTF 280 King Quad (98). It may fit other makes and models, or might be able to be fabricated to do so. 

Please review all pictures for more details and measurements.
