I installed lap belts in the 50, but wanted the top strap of the child seat to be hooked also.
Installed a brace/hook on the seat back

Video He Loved riding in that truck.
The brace is just flat bar that I bent a hook on the top and welded to the top and bottom. The hook is just round stock heated and bent. There may have been an easier way to do this, but I’m satisfied with the results. When he is riding I will remove the inside door handle.
