I’m fitting 3 point seat belts from a mid-80s XJS into my 88 XJS (I’ve removed passive belt system)
I’ve got the original bolt/spacer/lockwasher for the receptacle (Thanks Paul!), I’ve got some new grade8 bolts/lockwashers for the winder that goes behind the backseat quarter panel, and I’ve got some grade8 sleeved anchor bolts for the upper shoulder part so it can rotate.
I’m not sure what the floor anchor needs? Will just a grade8 bolt and lockwasher work? Or does it need a spacer or anchor bolt so it can rotate? And I assume I’ll find a hole to screw into on the floorboard under the carpet?
