some good ideas are to get a grease pencil (i believe thats what it is called) and some tape that wont leave sticky residue on the paint......this way you line up the lips n stuff (if its even a lip kit) and then hold them on with the tape and then trace the top of it so when you go to actually attach it you can see it is lined up perfectly. oh and at least 1 friend around is very very helpful....if its just bumper replacement, easy enough to do yourself, just unbolt, remove, put on, put bolts back, step back, love it, be happy.
