Hmm, well, I don't have a drawing but I just rebuilt both of one of my 88 Formulas headlights. Did you remove the entire assembly? Just how far did you go?
I find it easiest to remove the entire assembly and then remove the headlight motors. There are only three bolts holding the motors in the assembly. Two long and one short. Although I know where they each fit, I'm not sure I can accurately describe it but, it you do a little trial and error, it's pretty obvious. Then you have the one bolt on the radius arm, that moves the light up and down. Again, I'm not sure just how far you went but, you don't need to dis-assemble the whole mechanism to pull the motors out.
Might be easiest it you found another Fiero or similar pop up headlights still in a car and take a look before you start putting it all back together.
