Lets not make a mountain out of a mole hill. Simply put...the guy standing inside the chassis rails has a tool called the Bucker. (which reminds me of a "porta-power"). He sticks the hot rivet through the hole, sets the bucker in place, hits the switch to make it push on the rivet...the other guy hammers it in. Then the guy inside the rails hits the release button and moves it to the next rivet and the two of them repeats the process again.....like Bill says, take a goood luck at 6 sec...
