Might be hard to order one since you aren't at home. But RockAuto also has a fitment guide. The 3351028 100Amp fits mostly S-series and Fiero, but the 3341912 85A fit's a number of vehicles including same year Cavalier:

CHEVROLETCAVALIER1987
CHEVROLETCELEBRITY1988-1989
CHEVROLETS10 BLAZER1987-1989

Sorry, I'm not a big help on that. My general thought though is that the cases are fairly generic for these GM vehicles. Output might be a concern, but my thought is that basically anything that'll fit physically and have the correct plugs should get you home.
