These are the indicator stalks for the Ducati 750 F1 models. The original ones had a material defect and were prone to crumbling and falling apart. Thread is standard M10 x 1.5 (as per originals). These stalks are sold individually. Comes with 2 x self tapping screws.
NOTE: When you install these, first remove your lens cover, then disconnect the small wire connectors from the bulb holder. Pull the wires through your original stalks from the threaded end. To install these new stalks, screw them into your indicator just tight enough to secure the 2 pieces together. DO NOT OVER TIGHTEN! Now, stick the wires into the new stalk from the threaded post end - you are pushing the SMALL connectors through the threaded post. Clip the connectors back in place onto the bulb holder, screw the lens cover back on & you are done.
