Need Help
Im looking at 2 differnt sets of belts for my 72 and all look the same except the retractors. one set has  wiring but the boot is shaped at the floor at an angle. the secound set does not have any wiring and is more squared off. the tags on the belts both indicate they are from 1971.
did they change the angle of the boot mid year or is the boot with the angle not correct for a charger 1971 1972 ? this for the front bucket seats .

wired with stud on belt terminal are 72/73...the stud is where shoulder belt hooks onto. Wires are the sensors to the warning signal available on those models

71s are without wire and stud on belt terminal, since 71s warning signal is flasher timer kind and shoulder belt used its own female buckle
