WOW...5 turns lock to lock? That seems like a lot. Should be really easy to turn with no PS. I just put the UniSteer rack and pinion on the 64 Sprint I'm rebuilding and it only turns 2.5 lock to lock but has PS. Can't wait to try it out. I went with the rack unit since it's designed to get rid of the bump steer these cars had. I couldn't find much info either when researching the steering available. Mine has the Granada brakes , also.
