Need information

Hello all, hope everyone's doing good going into the new year. I need some help. My 71 Demon was missing the rear bracket that holds the two park brake cables going to the differential on the drivers side frame. It's just behind where the cable equalizer would be. Anyway I got the bracket but need a measurement from a Duster or Demon from the torsion bar cross member to the bracket. Mine apparently went bye bye when previous owner did the spring relocate. Thank you.
