I modified a Makita grip to make a shift knob. The parts, made from cast aluminum in-house, are firmly attached with adhesive and press-fitting. It has a moderate weight, and shift operation is smooth. One stainless steel low-head nut for positioning is included. The shift pattern is processed by electrolytic etching. I am confident that the quality is different from similar products, offering a sense of luxury. I believe it can pass a vehicle inspection, but there may be regional and inspection center differences. I cannot guarantee it. Please understand. This is a personally made item. There may be some errors (such as casting voids) in the aluminum parts. It is not recommended for those seeking the quality of a mass-produced product. I will post a test fitting (for myself, not the product for sale). The test vehicle is a LiteAce. Why not combine your familiar Makita power tools with a shift knob? Screw hole depth: Approximately 4 cm Screw diameter: M12 pitch 1.25 Please check the screw size of your vehicle before considering. Shipping is limited to the post office and will only be on weekdays. Thank you for your understanding. #MakitaGrip
