U can get to all bolts with out removing anything but you'll have no skin left on hands .. I just took grill reinforcement out in less than 20 minute but I have done them before . To start my rad support swap ..
Start on drivers side as the overflow tanks comes out easy . Once you figure what bolt holds outer bezel on (the fun one to find ) and remove bolts in grill area the bumper light /side light come out . The clips r easier to see for lights . Then go to pass side.
But as said the clips rust and with grill support laying out where see it will be worth the work .
I'm glad somebody asked this question, as a couple weeks ago I was going to take off the "headlight doors" or "trim" to paint them, but I had no flippin idea how. Alot of trouble for a little bit of paint. Good luck with swappin out those lights
