I made these years ago, so no step-by-step pics (if you can't figure it out, you probably shouldn't be playing with a welder ) Originally I had planned to run a cargo net between the 2 points on each side and wrap it around the top to help stop anything in the back from flying forward in an accident, just never got around to it
Materials:
1.5" chain (link size, duh )
1" long, 7/16" diameter, fine thread bolt
cut a link off your length of chain, weld it to the bolt head
I welded it with the cut side towards the bolt . . . you know, so the link doesn't bend and open up again. The tie-downs are threaded into the same hole that the Canadians used for the rear seat belt shoulder straps, so I don't think attachment strength sohould be an issue. BTW, the 1.5" chain links are the perfect size for nylon tie strap hooks - use whatever size you want.
oh yeah,
