IIRC off the top of my head...the 80s mixed and matched. I.E. some years had just a Top 40, other years he did do a Top X of X.
All I know for sure is: 1986 was the Top 86, straight from R&R. Part One is actually on Rick's phone app right now. 1989...actually I'm not completely sure if that year had any, as he did in fact do a Top 80 of the 1980s. But if 1989 had its own countdown, it would've just been a Top 40 - I do distinctly remember it being mentioned on here that the only large-scale countdown for 1989 was AT40's Top 100.

WT40 85, 87, and 88 year end shows were all just a top 40 although Rick also did a number ones of 85 as well. 86 was the top 86, and 89 had no year end countdown, Rick went with a top 80 of the 80s that year although it was interspersed with top hits of 89 as well. The co-host on decade end show was Taylor Dayne.
