You can see that the old bumper brackets have been cut off and capped and the lower air holes covered as well. My guy made very funky brackets to mount the new bumpers which I don't have pics of right now but will get.

Ms Triss had the dubious advantage of having been lightly rear ended before I got her, thus, unlike Rick it was easier for me simply to get a new rear valance to recreate the "humps" under the taillights. He did have to make a bracket for the bumper.
Rick put his signal lights in the existing fender holes. I had mine filled in and will be having him put in bugeye signals instead - a look I like better.
Having done all that, get pre-rubber bumper front springs (lower) and de-arch the rear springs an inch to get the proper ride height.
Bottom line is it's easy, not too costly and looks a hundred times better - go for it
PS - Not sure what the NJ laws are but if I were still in Florida where the car dosn't need to be certified in the same way I might have left the bumpers off all together.
