I got one from vintagecb750.com for my '78 K8 and it was absolutely perfect. Only thing was I think it had an extra ground female blade connector near the coils. I didn't plan on getting a new harness, but after 40 odd years of whoever hacking into it, even if I could fix it, it's just so much nicer to get a new one, and for $100 you just can't go wrong.
