The valence on a 69 drops off leaving the turn indicators on the car (they mount to the bumper). You will need to disconnect the side marker lights--just grab the wires/soft rubber close to the light housing and twist a 1/4 turn and they come out. There are a couple of bolts mounting to the fenders on each side vertically, a bracket on each side at the bottom mounting to a tab on the frame rail, a bolt in the center bottom of the valence mounting to the grill support/rad support, and two bolts each side mounting to the headlight bucket mounting tabs if they aren't broken off.
Fenders are as the previous guy mentioned, but add a bracket on each side with two bolts mounted to the radiator support and the headlight wiring harness to disconnect. You will also have to pull the grill and the center stuff below the grill. Not sure if it can be done leaving the bumper intact on the car, but I think so. Been a long time since I took mine apart, so this is all from memory. Good luck.
