Wide bed A pickup

[Modelacrazyq]

Hey all, I did a search but came up empty handed, I’m goin after a wide bed and steel cab tomorrow (3 hours 1 way) and I’m looking for pictures of how the wide bed mounts to the frame. I have a running chassis I’m putting the cab and bed on, I have experience with narrow beds but I’ve never seen the underside of a wide bed so any pics you might have will be a great help! The bed has a steel floor also but no wood that I can see, does the wood get sandwiched in the floor somehow? Thanks for the help!!
