What is the model year for Kenmore dryer 66902?

I think the model year for Kenmore dryer 66902 would be either 1989 or 1990. Ours is the original for our condo and the condo was built in 1989 and the Maytag washer was installed in 1989 or 1990 and so I am sure that the dryer would have been installed at the same time. Marilyn
