| Hi Ross, Im not familiar with the chassis pad which the engine mount attaches to on the RF, but from your pic it would appear that the flat area in the saddle of the mount does not have a corresponding flat area on the chassis bracket on which to sit. The original chassis pads of a Falcon or Mustang take all the engine weight and the long bolts should slide in & out freely(7/16" dia bolts). If there is no flat area the engine torque will tend to twist the mount around the long bolt axis and premature failure of the rubber will result.
