Are you sliding them under the black plastic fillers on the bumper itself? It is tricky to get that upper support under that plastic on the car. I've had better luck assembling the whole assembly (bumpers, upper support, lower support, and grill brackets)on a bench and mounting it the the bumper brackets on the car. I will try to post some pictures if I can find them
