I receive many questions about vehicle compatibility, but I don't work in the automotive industry, so please check by removing the part from your vehicle or by searching online. If purchasing multiple items, please use the bulk purchase feature. You will receive a ¥100 discount per item. Due to many requests for this grip for the Prius, I've created a version for M6, which was previously impossible because of the Φ7 opening, by embedding a special nut. This is a tapped Mac Tools driver grip (DG22), M6 P1.00mm. See the second photo for an example of installation on a 30-series Prius. Choose one color from the five colors in the first photo and specify the color in the transaction email. (Black, Green, Red, Yellow, Orange) *Black, Green, and Orange are out of stock and have the new logo. As a precaution during installation, completely remove any thread lock adhesive attached to the male threads on the vehicle side. The nut embedded in the shift knob is the same type used for camera tripods. Locktite is applied to prevent it from coming loose, and the hole depth is adjusted to prevent it from going in too far. However, the fixing method differs from that of a camera, so forcing it may cause the nut to move. A locking nut is also included (you don't have to use it). Using this will increase the overall height by the nut's height. The grip height is approximately 110mm. Although it is new, it has been modified, so it is treated as used. We can accommodate changes to thread diameters such as M10 and M12. (Please inquire via comments) Other colors and dimensions are also available. We also sell Mac Tools grip keychains that can be attached to cars and motorcycles. We generally do not accept price negotiations.
