In process of converting the lap belts to shoulder and Question on the fronts for mounting points- Does the upper buckle point utilize the "hidden bolt hole" behind headliner approx. 1/3 back in rear door OR is there another hidden hole in the pillar? Looks like the later models put them in the pillar, next to seat, but my 75 has the two high mounted bolt holes under headliner.
Same goes for retractor point- this needs to be vertical and I'm not sure if there is another mounting point down low, just whats in the floor.
Finally- any input on length, shoulder loop extension and sleeve greatly appreciated.
