I'm thinking about getting an aluminum crossover toolbox for my 3rd gen. The problem is finding one that fits. Some generically claim to fit all fullsize trucks from this year to that, but are only about 70" wide. I put my old one of that size in my 03' but it does'nt cover the bed rails completely, you can still see part of the stake pockets. So those of you with toolboxes, are you using 70" or 73" boxes?
