Hi, I have a full fendered '34 Roadster with a SBC. The front is M=II and no power steering, the steering wheel is a LeCarra Banjo,I think it is about 15 in. My car steers well with a little extra effort when standing still. I don't think I would go to power steering on this car. The manual rack seems to work fine. My car is glass but don't think there is that much difference in the weight of a steel car. Good Luck!
