I think the Calgary Fiero Club has all the Hemmings Factory Manuals online, too. The 84, 86, and 88 manuals cover about everything that pertains to the 85 and 87, except for the evap tank under the right rear fender well of the 87 and 88. The 84 is a beast of its own. The 86 has every variant that was on the 85 and later, like automatic, 4-speed, and 5-speed Getrag and Isuzu. The 86 manual probably has the most overall information. Of course, only the 88 manual has info on its unique suspension.
