Clem will answer, too, but the outboard front anchors share car seat anchor bolts and the inboard anchors have bolts through new holes in the floor boards with Juliano’s backup plates underneath. The rears are the same as the front inboard anchors. In order to have the buckles lay properly on the seats and not be twisted on your lap, we had to bolt the anchor plates reversed and double the belts back before passing behind the seat cushion.
