So recently my 1952 Wagon has become my daily driver......that's right my daily driver. I commute 30 miles one way to work and my top speed is around 45mph. I have a stock drive line with out an overdrive. What are my option as far getting more out of what I have? I do not want to do a swap but different gears or an overdrive is in my budget. What have you done and are any of you driving your wagons or trucks on a daily bases?
