How do if fit the chest straps of these, waists bolt to the seat fixing bolts but the cheat straps do not have any sort of braket, how ever the do have another strap which looks like it needs to be attatched some how.

 

If you have no fixings for the shoulder straps to enable you to clip onto the eye bolts ( behind your rear seats ), you might have a set which need a "Sparco Harness Bar"
