I've finished rebuilding my control valve and about to reinstall it. I seem to remember reading that you should leave about 5 exposed threads on the drag link when you thread the valve onto it. I took pictures but the stuff was so greasy it's very hard to make out the exposed threads.
Thanks Jeff

Not sure about the 5 thread deal but here's what I do know from the Ford manual. On t-birds it should be 9 1/2 inches from the center of the steering arm ball stud to the center of the left-hand spindle connecting rod ball stud. This dimension will keep the steering gear on the high point when driving in the straight ahead position.

They corrected it in the 1956 Manal, The 1955 has the wrong specification for that distance and you will wind up with the steering wheel 90 degrees off. They corrected it in a service bulletin but if you don't have those, You will be out of luck!

On page 310, figure 34 of the 1955 Thunderbird service manual it shows the distance specification as 9 inches which is incorrect. That's why I stated that the correct distance was 9.5 inches.

When I rebuilt my power steering control valve two years ago I threaded it as it shows in photo 23. My steering wheel was centered and the power steering operated as designed.
