'K8' is an October of '88 build for an '89 model (the prior year was called Avion -- in the catalog only I think -- there was a lawsuit and it was then renamed Ontare):

'F7' is a June of of '87 build (sorry, no catalog link).

Check the headbadges for a light, four digit stamping. This will be the assembly date code. The first three digits are the ordinal day of the year ('360' = the 360th day of the year), the last digit is the last digit of the year ('7' = 1987).
