The first things you need to ask yourself and tell us, how are you going to use the Cobra? Are you wanting to do long drives or short distance, are you going to do more highway or back roads driving? Lots of questions to answer before nailing down a specific drivetrain configuration. How bad is your knee? I have installed power assisted brakes and clutch systems that have kept people from selling their joy in life. If you like you can email me at
