I was on the fence about the 16:1 for my 65 Dart. I installed it last week direct bolt on non power steering and its great and so much tighter on the road at 60 mph. The steering isnt much harder at a stop (parallel parking) than the original 24:1. I really like it especially the price!
Great info/review. Those are the questions I wanted to ask about. How difficult is it to install with the motor and everything else already in the car?
