Re: Removing front bumper
You don't "need" the riveting tool. You can pull the pin on a new rivet with a pair of vise-grips and a box-end wrench. Just hold the rivet flush to the fender liner with the wrench and then pull back on the pin to expand the rivet behind the liner. That's basically all the rivet tool does.
It's an easy job, two hours TOPS to get it done. I think mine was off/on in about 45 total and that included figuring out the wrench/pliers trick for the rivets.
