Here's mine. Look on the passenger side,you can kinda see the seam on the bottom of the bed where it cracked.
Installing a rollpan is easy. Make all your marks first and double check. Mark everything out with a marker. Make sure when you cut out your old one,cut everything SMALLER first and then keep test fitting and cut as necessary. It will be more time consuming,but this way you won't get big ugly gaps. Under the tailgate,leave about an inch or two hanging down to weld the top of the rollpan to and to give it some extra strength.
