Very likely Dave.
The cable to the rear likely runs along the right hand sill (inside the car). You would have to remove the trim / leather etc. to follow it. Have a good check around the forward leaf spring mount that side, you may find where the cable goes through the panel below the parcel shelf. Just thinking out loud, but a possible pinch point?
