I belive you have the wrong webbing. It should have a wire in it.
The wire goes in the hole on the top of the cowl and is bentover under the dash. The wire on the bottom of the cowl is inserted in to the hole and bent over. Then you should have a threaded J- Hook. If I remember correctly in is about a 10-24 thread. The hook goes into the hole at the beltline and a washer and nut goes on inside the cab and draws the webbing down tight to the cowl. I hope this explanation makes sense.
