Hey Greg , your parts need list shows a carb to airbox connector with the part number listed as 06-4180 . I show that to be the MK III part . I have 2 new 06-2537 connectors I can send you , which my research shows are the correct ones for a pre Mk III commando . If you can check and confirm that I have what you need , shoot me a shipping address and I'll get them on their way .
Thanks
Ron
