I have the FSM (Factory Service Manual) for the 1987 and can send the schematics for the exterior lighting if you still need it.
If you damaged the front end, you could have easily have some headlight wires shorted to ground. If you could isolate the front part of the vehicle and concentrate on the rear (or visa versa), that would be a good way to start.
Initially you said some of the lights didn't work but now you're saying it is blowing fuses too? Not working is an easier problem to track down, blowing fuses, not so much but I do have the diagrams if you need 'em.
