Aluminum refrigerant line to rear cooling unit is leaking. Line is one piece line that is not

engineered to be replaced. Design of this line allows only for installation at time of factory

assembly of the vehicle. Line size is odd ball. Can not get fittings of proper size to make a repair. Continual recharging the refrigerant is expensive and only a temporary repair. This

vehicle has always been kept in a heated garage. the material chosen for this line is inappropriate for an off road vehicle. Looking for repair method.
