Hey guys I'm restoring a 77 k10 scottsdale stepside. When I got the truck it didn't have a bed on it, the cab has been painted and reinstalled. I got a bed at the local junkyard and it is being painted now, I've got all the crossmembers for the bed but I have no idea how the bed or the crossmembers bolt on. I have 2 different size crossmembers for the bed. If anyone has any pictures of how they are layed out or a diagram I would very much appreciate it. Thanks in advance
