As you answered the question I didn't have to look, I didn't remember partzilla going back that many decades.
Mental relief? Some might start a tire-oil-machining combination thread to keep you busy.

For ATVs, Partzilla actually goes back to 1980 at the earliest for Yamaha. 1976 for Honda. In the OP's case his year is a typo as the Big Bear started in 1987 not 1977.
