The speaker BARELY fits. In fact, I'm not happy with how little material there is between it & the wheelwell, but I didn't have any options to keep the nameplate on the grille horizontal like the fronts. The cupholder came from a '92-96 F-series Xcab or Bronco, and the cigar lighter will be switchable between OFF/ON/IGNITION from the center console (when that gets built). The shoulder belts are from an '86 Bronco and are attached with their original bolts to common hex nuts welded into the tube.
