This is a shift knob extension adapter. Total length is 100mm. M8 x 1.25 Stainless steel, unlike iron, is a hard material, so it has the disadvantage of being difficult to machine, but it is resistant to scratches, durable, and does not rust. *Please install at your own risk. Shipping is anonymous, so you can rest assured. Other sizes are also available. If you want an adapter, I can make it. Please comment. Made on a general-purpose lathe, please refrain from purchasing if you are sensitive or seek perfection. #car #motorcycle #adapter #extension #ordermade #caliber conversion #caliber change #oneoff #generalpurposelathe #truck #shiftknob #isuzu #fuso #underwaterflower #dekotora #dressup #jimny #prius #hino #extension
