I have a rotted out front crossmember and Im lucky enough to have one to put back in, my question is how they were attached from the factory (mine is really gone)...did they attach to the headboard as well? I'd imagine they're spot welded down through the middle to the floor? Any help is much appreciated

 

Cross members riveted at the factory, if replaced Ford dealership techs usually used bolts.

 

Thanks for the reply ND, but I guess I should've been more clear. I'm talking about the bed crossmembers/floor supports, whatever you call them in your neck of the woods
