The Date Code uses the Julian Calendar. A 17 would be the 17th day for the year (Jan-17th). A 113 would be the 113th day of the year (Apr. 23rd). 363 would be the 363rd day of the year (Dec 29th.) Picture below for referance.

Thanks guys,
Need to check the master cylinder that was in my car (5S275) when I bought it in 1988. The one in my car now I bought in
Denver Colorado 1991. Both have the adapters.

Found two in my garage, one dated 113 (probably the one from my car) and the second dated 135 which would be too late for my car.
