Man, you can't take a hint. KMC didn't exist in 1986. But you can find all the old tech docs for Shimano. I very clearly told Gene that he might have a problem if the 40 year old bike has the original chain, not that modern 6 speed replacement chains are wider.
You probably have Google on your computer. Try using it instead of doubling down on your ignorance.

The Sedis 8s were actually 7 speed chains because the Campy and Sachs 8 speed spacing was the same as 7. They probably worked fine on steeper Shimano mtb cassettes, though.
