Brand new production, better than anything else on the market. Stainless steel, brilliant.
Norton part number is 06-0453, to suit just about all Commando through 1974.
NOTE: This is modeled after the latest Andover spindle, with both the 1/4"-28 bolt hole and MK3-style wedge pin slots. It will fit seamlessly into both older transmission cradles and the updated cradles Andover now offers for retrofit.
