Greg.

It seems that the 40 303 relates to a 1974 manufacture date with the 0303 being a production number.

As for disc rotors, my 2c`s were made in 1977.

Your 8 is 1973 and the 9 is 1974.

All this information is contained in the Z1 enterprises site.

As far as the DOT goes I always thought it stood for the UK Department Of Transport. Meaning they were type approved for the UK market.

My front wheel says Takasago 1.85 X 19 6K 303 denoting 1976 manufacture for the US market.
No surprise as it`s a US import.
