I just take the old cable and housing,with the measurement I need it to be,to the local diesel truck repair shop,and have them build me a new one. Don't know anout your area,but here it cost me about 10% more that the parts stores get for a pre-made one,but it's a LOT more heavy duty. Probably never have to buy another one.
