Umm you shouldn't need to remove the fenders to pull the grille.
If memory serves me, 5 bolts on each side of the grill hold it to the fender. One underneath, and unbolt the rad/condenser. You should be able to remove it without disconnecting the lines to the condenser. And yeah, you'll need to unplug the lamps and unhook the harnesses clipped to the grille too.
Not as easy if the rad and such was out of the way, but it can be done.
