I've removed the bolt hidden by the door, the studs down at the bottom of the fender, the bolts that run along the inner edge of the fender/hood side edge, but there still seems to be a bolt holding my fender on, in the front, and for the life of me, I cannot find it.

I removed the grille and the bumper, because I remember from my 72 Cuda that there is some bolt hidden in that area but I can't find it on my Challenger.

Many thanks for any help.

Hey Mike. There's 2 bolts that go thru the radiator support. Drivers side, one is above the battery tray and one is below. Passenger side bolts may be hidden by washer jug or horns. They go in from the engine compartment side, into c-nuts on the fender. Good luck.
