I have completely disassembled the rear tub of my 73 88". The bed rails are off and look ok but the forward brackets on each side that appear to be used to mount seat belts are significantly rusted through. I have two questions:
  1. Are these required for anything other than seat belts? Meaning, if I decide to not replace them am I compromising anything other than rear seating safety? (I know I will have rivet holes to deal with)
  2. Can they be sourced or do they have to be repaired or made from scratch?


Thanks
Jack
