This is a used Original COUPLER for Flywheel to Driveshaft for Alfa Romeo GTV 6 and MILANO models. The LAST photo shows one in place on a motor for reference ONLY. We found it in the parts room of an old Alfa shop. A splined cast iron piece with indexing notch for driveshaft. It includes the pictured guibo and the bolt to tighten yoke on driveshaft. The guibo looks good, no apparent cracks, but may be best to replace it. As pictured, look closely at photos for details. Visit My Alfa Romeo GTV6 or MILANO / 75 Stores for more parts. I will combine multiple won items whenever possible to save on shipping costs, request combined invoice prior to making payment. Thank you.
