I did this awhile back to pin the crank on my SRT. It's pretty straight forward and self explanatory. Take your time and walk yourself through it. The only real "tricky' parts I can remember is it's real tight on the small upper bolt holding the top of the fender behind the facia. If your a big guy and/or have big hands it gets pretty tight up there on Challenger.(I used like three 1/4" long extensions and a swivel). Also there's a plastic support/reinforcement area at the bottom of facia area to lower fender area on Challenger. You have to give it a pretty good tug to disengage on Challenger and I was afraid I was gonna snap something.
Graphics are ALWAYS a good thing before going in. I'm sure the link will help a lot of guys make the leap if they have to.
