The next part gets to be a little frustrating, but with some tenacity you will be able to knock it out. Word to the wise, follow Bruce's lead as he installed the two black headed bolts to the bumper first although the instructions suggest attaching the silver bolt first. If you follow Bruce's guidance, then you should have no trouble attaching the silver bolt. See the picture here:

By attaching the two black screws first screwing ino the bracket, then all that is needed is the washer behind the bracket and then insert the sliver bolt. After that check the torques and then you should be able to insert the rubber caps into the fron of the bumper and you are done!
Last, but not least, feel free to drop me a PM if you have troubles.
