Shift knob conversion adapter. Male M12 x 1.25 Female M6 x 1.0 Unlike iron, stainless steel is a hard material, so it has disadvantages such as being difficult to process and expensive, but it is resistant to scratches, very durable, and does not rust. Even if products made of iron are coated or painted, scratches will inevitably cause rust, so we recommend stainless steel. *Please install at your own risk. Shipping is anonymous, so you can rest assured. Other sizes are also available. If you need an adapter, we can make it. Please comment. Made with a general-purpose lathe, please refrain from purchasing if you are sensitive or seeking perfection. #Car #Motorcycle #Adapter #Extension #CustomMade #DiameterConversion #DiameterChange #OneOff #GeneralPurposeLathe #Truck #ShiftKnob #Isuzu #Fuso #UnderwaterFlower #Dekotora (Decorated Truck) #DressUp #Jimny #Prius #Hino #Extension
