Removing 88 Justy front bumper

[Kurzer]

I spent a good part of the evening and most of the night trying to get the front bumper off. There are four bolts, two on each side, on top under the trim, under the headlights. I think I tried every tool in the garage to get to those bolts, I even tried some things from the kitchen... with no luck. My Chilton is next to worthless. Does anyone know how to remove these bolts? I'd be very interested.

 

TIA!!!
