As best we know, according to the vin directory, only the 9/69 sandcasts had the riveted on alumuinum vin plate. To date, we have not noted (yet) any 8/69 machines with this plate. To the best of our knowledge, except for 9/69 sandcasts, an adhesive sticker was used and did not have vin on it. All CB750's have the vin stamped on the LH head stock. The stickers and riveted on plates were on the RH head stock. Perhaps Yamiya, DSS or CMC has them..... ?
Would be great to hear if anyone has an 8/69 sandcast with a riveted on plate.
Some time ago, we requested owners to check their RH headstock so we could get a better idea when the earliest frame vin was than had this riveted on plate.
