My front seatbelt/shoulder harness setup has no guide from where they mount on the floor just behind the driver'sseat. It's just bolted on and hanging. I have gotten the guides for the top of the headrests (not installed yet) but wonder if I'm supposed to have guides from the back floor too. Anyone know if I should have these? If so any pictures of what they look like? What years would work right in my 79? I've included 2 pictures of my setup-one from inside and one from outside.
