Even with all the bolts removed, you'll find that the front fenders are "locked" into place. You may have to loosen or remove the radiator supports and get the grille out of the way to have enough play to unhook the front edge. The edge where the fender meets the cowl is also a tricky slip-fit if the inner fenders are bolted tight to the firewall; you may need to loosen those bolts. When I was trying to pull the fenders off most of the lower bolts were rusted to the point of being indistinguishable from the sheetmetal; that's when I coined the phrase, "Pass the cutting torch, I'm done f***ing around."
